A Comprehensive Explanation of the Core Technologies and Applications of the 50T Start-up Boiler for 2×1000MW Ultra-Supercritical Units

I. Positioning and Core Role of the 50T Start-up Boiler

In a 2×1000MW ultra-supercritical large-scale thermal power project, the 50T start-up boiler is not merely an auxiliary component of the main unit, but rather a core pre-installed device ensuring the safe and efficient startup of a megawatt-class unit. The main steam parameters of ultra-supercritical units far exceed those of conventional subcritical units, requiring extremely high temperature and pressure stability of the steam during cold starts. Relying solely on the main unit's own water circulation system makes it difficult to quickly produce qualified steam that meets the requirements for turbine start-up, pipe warm-up, and generator warm-up. The core value of the 50T start-up boiler lies in its ability to independently produce auxiliary steam with matching parameters before the main unit ignition. This significantly shortens the main unit's startup time, reduces fuel consumption during startup, and prevents thermal shock caused by mismatched steam parameters, effectively protecting thick-walled critical components such as the turbine rotor and main steam pipes, thus extending the overall service life of the main unit.

II. Technical Characteristics of the 50T Start-up Boiler Adapted to 1000MW Units

Designed to meet the specific needs of 2×1000MW ultra-supercritical units, this type of 50T start-up boiler features extensive optimizations, fundamentally different from ordinary small-tonnage industrial boilers. It generally adopts a modular integrated design, with core components such as the furnace, heating surfaces, and burners pre-assembled in the factory. Upon arrival at the project site, only interface connection needs to be completed for commissioning. Compared to traditional bulk boilers, this shortens the installation cycle by nearly half and significantly reduces on-site construction safety risks. To match the start-up curve of ultra-supercritical units, its steam parameters can be flexibly adjusted over a wide range, stably outputting high-temperature, high-pressure steam that meets the main unit's start-up requirements. It is also equipped with a low-NOx combustion system, easily meeting the ultra-low emission standards required for current thermal power projects, fully complying with clean production environmental protection requirements.

III. Standard Commissioning Procedures and Key Control Points for the 50T Start-up Boiler

The commissioning of the 50T start-up boiler follows strict operating procedures, with each step directly affecting the safety of subsequent main unit startup. Before ignition, the interlocking protection of the entire system must be verified, including simulation tests of all safety devices such as water level protection, pressure protection, and flameout protection. Simultaneously, individual test runs of auxiliary equipment such as feedwater pumps, induced draft fans, and oil pumps must be completed to confirm that all equipment is in normal standby condition. During the water filling stage, the difference between the feedwater temperature and the boiler drum wall temperature must be strictly controlled to not exceed the specified threshold to avoid excessive initial thermal stress on thick-walled components. After ignition, the boiler water temperature should be gradually increased at a rate not exceeding 2℃/min, with real-time monitoring of boiler water quality throughout. Only when indicators such as conductivity, iron ion content, and pH value all meet the standards can steam parameters be further increased to prepare for subsequent steam supply to the main unit system.

IV. The Operational Value of the 50T Start-up Boiler for 1MW Units

The proper use of the 50T start-up boiler can bring significant comprehensive benefits to the 2×1000MW ultra-supercritical units. During the project's infrastructure commissioning phase, it can independently provide a stable steam source for pipeline purging and chemical cleaning without requiring early start-up of the main unit, significantly reducing fuel oil and plant power consumption during the commissioning phase. During routine peak-shaving start-up and shutdown of the unit, the start-up boiler can provide auxiliary steam to the shaft sealing system and deaerator in advance, making the start-up process of the main unit smoother and significantly reducing equipment losses during start-up and shutdown. Over the long term, this not only reduces the start-up cost of the unit but also effectively improves the peak-shaving flexibility of the entire power plant, enhances the unit's adaptability to grid load fluctuations, and lays a solid foundation for the long-term safe and economical operation of megawatt-class ultra-supercritical units.

50-ton Electrode Steam Boiler: A Thorough Guide from Principles to Practical Application

I. What is an Electrode Steam Boiler?

An electrode steam boiler is a highly efficient steam generator that directly introduces high-voltage current into a water medium, utilizing the water's high resistance to instantly produce heat. Its heating voltage is typically medium-voltage electricity, ≥6kV, commonly 13.5kV, while the power control voltage is 380/220V. Therefore, electrode boilers require two power sources—one medium-voltage and one low-voltage—which is the most fundamental difference between them and ordinary electric boilers.

Compared to traditional combustion boilers, electrode boilers achieve near-zero energy loss in energy conversion, with a thermal efficiency exceeding 99%, and actual measured energy efficiency reaching 99.65%. In short, every kilowatt-hour of electricity is fully utilized, directly converted into steam heat energy.

II. Core Parameters of a 50-Ton Electrode Steam Boiler 50 tons of steam refers to a rated evaporation capacity of 50 tons per hour.

This means the boiler can output 50 tons of saturated or superheated steam per hour, sufficient to support high-load scenarios such as large-scale industrial production, hospital steam supply, and centralized heating.
Evaporation capacity: 50 t/h
Rated steam pressure: Typically 1.25 MPa (customizable upon request)
Rated steam temperature: Approximately 194℃ (saturated steam), superheated steam can be customized to higher temperatures
Thermal efficiency: Over 99%
Heating voltage: 6~20kV (high power generally requires 13.5kV)
Adjustment range: 10%~100% stepless adjustment, extremely high power control precision
Landscaping: Achieves over 10 times the power of traditional electric boilers within the same volume, single unit power can reach 50MW or even higher

III. Two main structural forms: Submerged vs. Jet-type

Electrode boilers are mainly divided into two types according to their structure: fully submerged (immersion type) and jet-type:

Fully submerged electrode boilers: The electrodes are directly immersed in the boiler water. Power is adjusted by changing the contact area between the electrode and the water, rather than adjusting the water flow or water level, thus resulting in more precise power control. This structure has a small circulating water volume, requiring only replenishment of water lost through evaporation. The boiler water conductivity is generally required to be approximately 100μs/cm, resulting in superior steam quality. However, because the electrodes are in direct contact with the boiler water, the electrode contact area must be insulated from the boiler's metal shell.

Jet-type electrode boilers: Boiler water is directly sprayed onto the electrodes for heating, and the electrodes are "relatively isolated" from the metal shell, eliminating the need for shell insulation. However, the sprayed water volume is extremely large, reaching over 1000 m³/h at high power levels. The boiler water conductivity needs to be approximately 1700 μS/cm, and the steam salinity is higher than that of submerged boilers.

Currently, Chinese companies, represented by Fangkuai Boiler, are using fully submerged electrode boiler technology in their 50-ton steam projects exported to the Middle East, and have obtained international authoritative certifications such as ASME and CE.

IV. Why are electrode boilers a "hardcore contender"? Five major advantages address pain points: First, overwhelming efficiency.

A thermal efficiency of over 99% at the 50-ton steam level means significant annual energy cost savings for companies. For example, in a Middle Eastern hospital project, in an extreme environment with surface temperatures exceeding 50°C, the maximum steam output with minimal electricity directly translates into economic benefits for the customer.

Second, zero emissions and true environmental friendliness. Electrode boilers use electric heating tubes for preheating from cold to hot, with no combustion or exhaust gas during operation, truly achieving zero emissions. This is the core reason for their successful application in nuclear power plant auxiliary boilers.

Third, extremely high safety ceiling. When the boiler is short of water, the current path between the electrodes is automatically cut off, eliminating the risk of conventional boilers burning out due to water shortage. In case of overpressure, the overpressure interlock protection device automatically sends a signal to stop heating, fundamentally preventing dry-burning accidents.

Fourth, stepless adjustment and extremely fast response. The power adjustment range is 10% to 100%, allowing for real-time stepless adjustment according to the actual load, making it particularly suitable for fluctuating energy scenarios such as wind power and photovoltaic power consumption, and also applicable to thermal storage systems for centralized heating in coal-to-electricity conversion projects.

Fifth, extremely low maintenance costs. Apart from a small-power magnetic pump for adjusting the liquid level, electrode boilers have almost no moving parts, resulting in extremely high reliability and a significantly lower daily maintenance workload compared to traditional boilers.

V. Operating Procedures for a 50-ton Electrode Steam Boiler

Pre-start Preparation: Inspect the boiler for external damage and ensure there are no leaks (water or gas). Confirm that the medium-pressure power supply (6-20kV) and low-pressure control power supply (380/220V) are normal. Check the electrode condition, water level gauge, safety valve, pressure gauge, and other safety accessories for proper functioning. Confirm that the boiler water conductivity is within a reasonable range (approximately 100μs/cm for fully submerged boilers). The feedwater must be softened standard water.

Start-up Procedure: First, start the control system and low-pressure power supply, then connect the medium-pressure power supply. Preheat the boiler water to the operating temperature using the heating elements (the electrodes are not yet energized at this time). Once the boiler water temperature reaches the standard and the conductivity stabilizes, gradually activate the electrode heating. After startup, warm up the heating elements before increasing the pressure; this order is crucial.

Operation Monitoring: Monitor key parameters such as steam pressure, water level, boiler water conductivity, current, and voltage in real time. Excessively high conductivity can cause breakdown accidents, while excessively low conductivity results in insufficient heating power; both must be strictly controlled within the set range.

Shutdown Procedure:

First, gradually reduce the electrode power (to below 10%). Once the steam pressure drops to a safe range, shut off the medium-pressure power supply, then shut off the low-pressure power supply and feedwater valve. After shutdown, wait for the boiler to cool down before performing any maintenance.

VI. Daily Maintenance: Four "Musts" Cannot Be Ignored

Daily blowdown is mandatory. Blowdown should be performed once a day to ensure clean boiler water and prevent scaling and conductivity drift.

Daily inspection of safety valves is mandatory. The safety valve lever should be pulled at least once a month to check its flexibility, and moved daily to prevent rust and malfunction.

Regular water quality testing is mandatory. Boiler water must be softened standard water. Regularly monitor the boiler water conductivity to ensure it remains stable within the set value. For fully submerged boilers, the heat transfer medium water is added once and operated in a closed system, without contact with the outside environment, preventing electrochemical corrosion and maintaining constant conductivity.

Regular tightening of electrical connections is mandatory. Regularly check the tightness of electrode wiring, medium-pressure cabinet protection signals, and the wiring of all electrical components in the control cabinet to prevent poor contact and burnt wires.

In addition, operators must hold a "Special Equipment Operator Certificate" and undergo professional training before being allowed to work. Power must be disconnected and pressure released during maintenance and repairs; this is an ironclad rule.

VII. Typical Application Scenarios

The application scope of the 50-ton electrode steam boiler is extremely broad:

Medical and Health: For example, in a large hospital project exported to the Middle East by Fangkuai Boiler, the 50-ton electrode boiler supports green medical steam supply;
Wind and Solar Power Consumption: Combined with thermal storage tanks, it achieves energy storage during off-peak hours and heat release during peak hours, solving the problem of wind and solar power curtailment;
Coal-to-Electricity Central Heating: The electrode boiler + temperature-stratified thermal storage tank + peak-valley electricity intelligent control system provides strong support for the national coal-to-electricity strategy;
Nuclear/Coal Power Auxiliary Boilers: Achieving zero emissions from power plant auxiliary boilers, it has been applied in third-generation nuclear power projects such as "Guohe-1";
Industrial Production: Steam supply for various industries such as food processing, chemicals, textile printing and dyeing, pharmaceuticals, and semiconductors.

VIII. In a nutshell, the 50-ton electrode steam boiler, with its exceptional efficiency of over 99%, zero-emission environmental friendliness, and near-unbeatable safety features, is redefining the technical standards for large-capacity steam supply. When "Made in China" electrode boilers are deployed in Middle Eastern hospitals and nuclear power plants, they demonstrate not only technological depth but also the confidence of China's high-end equipment in going global.

High-Efficiency Energy-Saving Coupled Thermal Systems: A Breakthrough Path for Technological Integration and Green

Transformation Driven by both global energy transition and the "dual carbon" goal, high-efficiency energy-saving coupled thermal systems, with their advantages of energy complementarity, system integration, and intelligent control, are becoming a key technological path in industrial heating, building heating and cooling, and district energy sectors. This system integrates multiple heat sources (such as air source, ground source, solar energy, natural gas, and industrial waste heat), combined with high-efficiency heat exchange technology and intelligent algorithms, to achieve cascaded energy utilization and dynamic optimization, significantly improving energy efficiency and reducing carbon emissions. The following discussion covers four aspects: technical principles, core innovations, application scenarios, and future trends.

I. Technical Principles: Multi-Energy Complementarity and System Integration

The core of high-efficiency energy-saving coupled thermal systems lies in "multi-energy complementarity" and "system integration." It couples different heat sources through physical or chemical methods to form a composite energy network with complementary advantages:

Heat Source Coupling Logic
Air Source + Gas Boiler Coupling: In cold regions, the air source heat pump serves as the primary heat source, and the gas boiler as a supplementary heat source. When the ambient temperature drops below -5℃, the system automatically switches to a dual-stage operation mode. The air source heat pump provides low-temperature water at 15-30℃, and the water source heat pump further compresses and heats it to 60-80℃, achieving efficient heating. For example, after adopting this mode, a project in Beijing reduced winter heating energy consumption by 30% and carbon emissions by 25%.

Solar + Ground Source Heat Pump Coupling: Solar collectors supplement soil heat for the ground source heat pump in summer and directly provide domestic hot water in winter. An eco-residential area in Guizhou achieved 45% energy savings and a 40% reduction in annual operating costs compared to traditional gas boilers using this system.

Industrial Waste Heat + Heat Pump Coupling: Steel companies utilize waste heat from blast furnace gas to drive absorption heat pumps, converting waste heat into 60℃ hot water for heating, while simultaneously recovering condensate waste heat for power generation. One project saved over 50,000 tons of standard coal annually and reduced carbon dioxide emissions by 120,000 tons.

System Integration Forms:

Series Coupling: Heating return water passes sequentially through an air source heat pump and a gas boiler for relay heating. Suitable for scenarios with small system flow variation ranges.

Parallel Coupling: Return water passes through two heat sources simultaneously, mixes, and is then supplied to the terminal. The required circulation flow rate from the heat source equipment must be met.

Secondary Pump Coupling: Heat sources are decoupled through a balancing pipe and an independent circulation pump, suitable for systems with large differences in flow rate requirements. For example, after adopting this mode, an industrial park saw a 20% improvement in system stability and a 15% reduction in maintenance costs.

II. Core Innovations: Materials, Structure, and Intelligent Control

The performance improvement of high-efficiency, energy-saving coupled thermal systems relies on three major technological innovations:

Materials and Structure Optimization
New heat exchange materials: The application of materials such as graphene composite coatings and silicon carbide ceramics increases heat exchange efficiency by 15%-30%. For example, a chemical plant saved over 5 million yuan annually in steam costs after adopting graphene-coated heat exchangers.

Microchannel Heat Exchangers: Achieving a large heat exchange area through extremely small hydraulic diameters significantly improves volumetric efficiency, suitable for space-constrained scenarios.

Plate and Shell Heat Exchangers: Combining the high efficiency of plate heat exchangers with the pressure-bearing advantages of shell and tube heat exchangers, meeting the requirements of high-pressure conditions.

Enhanced Heat Transfer Technologies

Passive Enhancement: Inserting twisted strips or spiral coils into heat exchange tubes, or processing the surface with pits or corrugations, induces secondary flow in the fluid, enhancing disturbance.

Active Enhancement: Applying electric or magnetic fields, or causing surface vibration, suitable for special operating conditions (such as supercritical CO₂ power generation systems).

Intelligent Control Systems

Dynamic Optimization Algorithms: Real-time monitoring of ambient temperature, energy prices, and heat load demand, dynamically adjusting heat source output through AI algorithms. For example, after adopting an intelligent control system, a data center achieved a 25% increase in energy efficiency ratio (EER) and annual electricity savings exceeding 1 million kWh.

Digital Twin Technology: Constructing virtual models of equipment to achieve fault prediction and health management, providing 48-hour advance warnings and reducing unplanned downtime.

III. Application Scenarios: Covering All Fields from Buildings to Industry

High-efficiency, energy-saving coupled thermal systems have been widely applied in multiple fields, forming differentiated solutions:

Building Heating and Cooling

Residential Communities: Solar + ground source heat pump coupled systems provide stable heating for cold northern regions while addressing soil thermal imbalance issues.

Commercial Complexes: Photovoltaic power generation + ground source heat pump coupling systems achieve "self-consumption with surplus electricity fed into the grid," reducing dependence on the power grid. For example, after adopting this model, a commercial complex reduced annual carbon emissions by 50% and operating costs by 35%.

Industrial Waste Heat Recovery
Iron and Steel Metallurgy: Blast furnace gas waste heat power generation and process water heating systems increase energy self-sufficiency by 30%.

Chemical Industry: Waste heat recovery from distillation tower tops preheats raw materials, reducing energy consumption by 15%-20% while meeting the precise temperature control requirements of sterilization and drying processes.

Regional Energy Stations
Multi-energy complementary composite systems: Integrating solar, air, geothermal, and natural gas energy, these systems achieve optimal energy efficiency through intelligent control systems. For example, after adopting this system, an industrial park reduced overall energy consumption by 35% and carbon emissions by nearly 50%.

IV. Future Trends: Intelligentization, Greening, and Large-Scale Development

With technological iteration and policy support, high-efficiency and energy-saving coupled thermal systems will exhibit the following development trends:

Materials and Process Breakthroughs: Hydrogen-resistant and ammonia-corrosion-resistant material systems will support green hydrogen production and ammonia fuel power systems, expanding the application of equipment in the new energy field.

Deep Integration with AI: IoT-based smart energy management systems will enable collaborative operation and energy efficiency management of large-scale heat exchange networks, improving response speed by more than 50%.

Policy and Market Drivers: Under the "dual carbon" target, coupled systems will become core equipment for industrial green transformation, with a continuously expanding market size. It is estimated that by 2030, the global market size for high-efficiency and energy-saving heat exchange units will exceed US$100 billion.

Conclusion: High-efficiency and energy-saving coupled thermal systems, through multi-energy complementarity, system integration, and intelligent control, have reconstructed the technological paradigm of traditional thermal systems. They not only provide a practical tool for industrial energy conservation and energy structure transformation but also carry the key function of intelligent and low-carbon development of future energy systems. With the deep integration of materials science, digital technology and energy systems, this system will continue to drive the transformation of energy use towards high efficiency and cleanliness, injecting strong momentum into global sustainable development.

Boilers are essential for keeping homes and businesses warm and comfortable, but when they start shutting off unexpectedly, it can be frustrating and confusing. Understanding the cause of frequent shutoffs and knowing how to troubleshoot them can save time and money. This article explores common problems that cause boilers to shut off and provides practical solutions to fix them.

Troubleshooting Guide: Why Your Boiler Keeps Shutting Off

The development of social science and technology and technical means has promoted the rapid development of the breeding industry. People obtain meat, eggs, milk, wool, cashmere, hides, silk and medicinal materials from poultry such as chickens, ducks and geese through artificial breeding. For many farms, maintaining a constant temperature living environment for poultry is a top priority.
 
How to choose the type of hot water boiler for heat preservation in farms, Fangkuai Boiler can give you the most sincere guidance and advice.
 
Taking a shrimp farm as an example, we will focus on how users in the aquaculture industry should choose suitable hot water boilers.
 
Generally speaking, shrimp farming requires "cold water", but this "cold water" refers to the natural water temperature in a normal environment, that is, a temperature between 10-20 °C. However, in winter, it is necessary to start the hot water boiler equipment to maintain the temperature of the shrimp pond and ensure that the shrimp can survive normally.
 
In order to meet the needs of the livestock for the environment and diet, a device that can output heat in a lasting and stable manner is required. We can see that in many large farms, one or several steam or hot water boilers will be equipped for the livestock of the farm.
 
The shrimp farm that cooperated with Fangkuai Boiler this time needs to use a boiler to maintain the constant temperature of the shrimp pond. According to the knowledge of Fangkuai boiler sales consultant, the shrimp farm has a total pool volume of 20 tons. The boiler is mainly used in winter, and the water at subzero temperature needs to be heated to about 10°C. After calculation, the technicians of Fangkuai Boiler concluded that a half-ton atmospheric pressure hot water boiler can meet their needs. For this reason, we provided a boiler with an output of 0.35MW (that is, a half-ton capacity). Atmospheric pressure vertical gas hot water boiler (CLSH0.35-95/70-Q). The adjusted hot water boiler can maintain a temperature difference of 14°C between the inlet and outlet water and maintain a constant temperature in the shrimp farm's pool. Combined with the actual situation of the user's project site, the natural gas interface has not yet been connected to the local area. We have customized a plan for using liquefied petroleum gas. The fuel is transported through canned transportation. There is no need to specially prepare a fuel storage site, and it is very clean and convenient to use.
 

Guidance Scheme for Selection of Hot Water Boilers for Thermal Insulation of Farms

According to the structural design, the use of atmospheric hot water boilers should be of no risk. This is mainly due to the fact that the top of the atmospheric hot water boiler is open to the atmosphere, and the internal pressure is always the same as the outside. Many residential and breeding centers choose to use this type of boiler.

Although the safety of atmospheric pressure hot water boilers is very high, this does not mean that the furnace personnel can be negligent. A relatively old steam boiler located in a fish farm in Wangtan Village, Rudong Town, Rudong County, exploded due to improper operation of the boiler operator.

When using a normal pressure hot water boiler, pay attention to the regular observation of the water level to avoid low water level and dry burning. Otherwise, there will be certain dangers, and the service life of the boiler will be seriously reduced. Boiler operators should pay attention to the following matters:
       1. Strictly implement various rules and regulations, earnestly study the professional knowledge of boilers, continuously improve the level, and ensure the safe and economic operation of boilers.
       2. After the normal pressure hot water boiler is put into use, the unit and individual may not change the boiler structure, valve and pipeline system without authorization.
       3. Inspect and inspect various equipments according to regulations before taking over, including: water level of water tank (hot water tank, expansion water tank), energy consumption (boiler gas meter), thermometer (hot water tank temperature, boiler heat medium water temperature), etc. Check the operation records, check the equipment, and learn more about the boiler operation when you transfer the shift.
       4. The succession personnel will go to the boiler room in advance to prepare for the work according to the regulations, shifts and prescribed time, and understand the boiler operation.
       5. The shifter should prepare in advance, carry out serious and comprehensive inspections and investigations, and keep the boiler running normally.
       6. The shifting staff should introduce the relevant problems of equipment operation, water quality and boiler discharge to the successor. If the handover procedure is not completed, the handover personnel must not leave the job. 7. Keep the boiler body clean when the boiler is running, no dirt, no leakage, no rust and corrosion, and fill in the equipment maintenance record carefully and in detail.
       8. The boiler room is one of the key departments of the boiler unit. Except for the boiler room staff, relevant leaders, and safety, security, and department management personnel, other personnel are not allowed to enter without permission.
       9. It is forbidden to store inflammable, explosive and other miscellaneous items in the boiler room. It is necessary to install oil drums and oil pots with a small amount of lubricating oil and cleaning oil. Store them at the designated place and pay attention to check whether there is explosives in the burning.
       10. The boiler room should be equipped with fire-fighting equipment, carefully managed, do not move or use it for other purposes.
       11. The floor, walls, doors and windows of the boiler room are always kept clean and hygienic.
       12. The supervisors should check the operation records and environmental sanitation regularly and irregularly, find problems and solve them in time.
       13. Go to work on time according to the prescribed time, do a good job of shifting records, and do not leave the job casually.
       14. It is strictly forbidden to drink alcohol, sleep, gamble, and fight in the boiler room.
       15. After equipment failures and accidents are reported in time (timely reported to the person in charge at night), the written accident report is written in a realistic manner. After the investigation is clear, after the responsibility is clarified, the accidental loss is caused to the dereliction of duty, and the responsibility is handled.

How to make the normal pressure hot water boiler operate safely?

There are three reasons for the explosion of a gas boiler: gas (fuel), air and heat. Once the three reach a certain level, it is not far from the explosion of the boiler.

The key to preventing the explosion of gas boilers is to prevent the three from reaching certain limits at the same time. Among them, air is ubiquitous, it is very difficult to remove this condition, so the focus of explosion-proof is concentrated on gas and heat sources. Therefore, almost all gas explosion-proof technologies at this stage focus on how to treat gas and heat sources.

A large number of accidents indicate that the explosion of the gas boiler boiler or flue site is caused by the accumulation of gas and air in the furnace or flue, and the fire or high-temperature heat source. The combustible mixture is obviously mixed with air from the air. Forming. Therefore, the core of preventing gas boiler explosion is to prevent the boiler from entering the furnace when it is not running (no flame in the furnace); and it should be noted that the boiler must be "fire and other gas" when it starts, that is, the gas is first supplied and then ignited to form a heat source.

To this end, "Steam Boiler Safety Technical Supervision Regulations" and "Hot Water Boiler Safety Technical Supervision Regulations" clearly stipulate that: gas (including fuel, pulverized coal) boilers must be equipped with reliable ignition program control and flameout protection devices; Explosion-proof doors should also be installed in inflammable and explosive parts such as furnaces and flue ducts. The first half of the regulation is actually based on the mechanism of the explosion to prevent the formation of a mixture of gas and air, and to ensure the realization of "fire and other gas"; the latter part is used as a remedy, once the furnace or flue explosion, through the explosion-proof door Reduce the damage caused by the explosion.

How to prevent gas boiler explosion?

Pickling is the main method for removing a large amount of oxidizing substances and corrosion products inside a gas boiler, and also has the effect of eliminating scale. The pickling process is usually carried out after 1-3 weeks of boiler operation. FANGKUAI Boiler summarizes the steps of boiler pickling for your reference and understanding.

First, cleaning tools
       Boiler energy saver, steam drum, water wall, hydrochloric acid, ammonium bifluoride.

Second, the cleaning method
       1. First, at the beginning of the pickling work, the boiler's economizer, steam drum and water wall are filled with demineralized water.
       2. The boiler is ignited. When the temperature of the boiler rises to 70-80 ° C, the boiler is turned off, and then the pickling operation can be performed. Before the pickling operation, the superheater should also be recharged with demineralized water until the water overflows into the steam drum to prevent acid or acid vapor from being introduced into the superheater.
       3. When the acid is charged into the boiler, the boiler should not be ignited under any circumstances. The steam drum and other venting holes should be opened to remove the hydrogen generated by the reaction of acid and iron. Before making sure that the hydrogen has dissipated, avoid open flames or use electrical equipment that generates sparks to avoid the risk of hydrogen explosion.
       4. Finally, after the acid filling is completed, let the boiler and economizer soak for about 6 hours in the solution, then drain the acid and rinse the superheater with demineralized water. The acid is discharged. After the acid is drained, the boiler feed water pump is operated, and the water of one economizer is filled into the boiler to prevent the water supply shutoff valve from leaking.

Third, matters needing attention
       The gas boiler can be pickled with 5% hydrochloric acid with 0.25% ammonium difluoride inhibitor added. The acid solution is injected into the boiler through the pickling joint on the steam drum down pipe, and the acid filling of the economizer is carried out through the recirculation pipe. The filling of the acid solution should be carried out until the liquid level in the steam drum temporary water level gauge rises significantly until the liquid level rises above the cyclone separator, but it should be noted that the acid liquid cannot enter the superheater, otherwise it will cause serious damage.
