Hot Water Boiler vs Water Heater: What’s the Difference and Which One to Choose?

Hot Water Boiler vs Water Heater: What’s the Difference and Which One to Choose?

Introduction

When it comes to heating water or your home, two common systems often come up: hot water boilers and water heaters. Although they sound similar, these appliances perform very different functions. Many homeowners and building managers confuse them, thinking both serve the same purpose.

This guide will help you clearly understand the difference between a hot water boiler and a water heater, how each works, their advantages, costs, and which system is best suited for your home or business.

What Is a Hot Water Boiler?

A hot water boiler is a heating system designed primarily for space heating. It heats water and circulates it through pipes to radiators, baseboard heaters, or underfloor heating systems throughout the building. As the water cools, it returns to the boiler for reheating, creating a continuous loop of warmth.

Common Types of Boilers

  • Gas-fired boilers – Efficient and popular for both homes and commercial buildings.
  • Oil-fired boilers – Ideal for areas without natural gas supply.
  • Electric boilers – Compact and clean but may cost more to run.
  • Biomass boilers – Eco-friendly option that burns wood pellets or chips.

Boilers are often used in colder climates where consistent, high-output heating is needed. They’re designed to deliver powerful and efficient heating over large spaces.

What Is a Water Heater?

A water heater, on the other hand, provides domestic hot water for everyday use — such as showers, dishwashing, and laundry. Unlike boilers, water heaters don’t heat your home; they simply heat water for personal or commercial use.

Main Types of Water Heaters

  • Storage Tank Water Heaters – The most common type, storing and maintaining a set volume of hot water (usually 30–80 gallons).
  • Tankless (On-Demand) Water Heaters – Heats water instantly as it flows through the unit, saving space and reducing standby energy loss.

Water heaters are generally smaller, cheaper, and easier to install than boilers, but they’re not designed to provide home heating.

Key Differences Between Boilers and Water Heaters

Feature Hot Water Boiler Water Heater
Purpose Space heating Domestic hot water
Output Hot water for radiators or underfloor heating Hot water for faucets and appliances
Fuel Options Gas, Oil, Electric, Biomass Gas, Electric
Efficiency Range 80%–95% AFUE 60%–90% Energy Factor
Installation Cost Higher Lower
Maintenance Annual service required Low to moderate
Lifespan 15–25 years 8–15 years

Efficiency and Cost Comparison

When comparing boiler vs water heater efficiency, boilers generally win. High-efficiency condensing boilers can reach up to 95% AFUE, meaning they convert almost all fuel energy into heat. Water heaters, especially traditional tank models, typically have lower efficiency due to heat loss from stored water.

However, installation cost is usually higher for boilers:

  • Boiler installation: $3,000 – $8,000+
  • Water heater installation: $800 – $3,000

Operating costs depend on fuel prices, insulation, and system usage. Over the long term, boilers tend to offer better efficiency for heating, while tankless water heaters save energy for domestic hot water.

Which System Is Right for You?

Choosing between a hot water boiler and a water heater depends on your home’s layout, climate, and heating requirements.

Choose a Hot Water Boiler If:

  • You live in a cold climate and need reliable, whole-house heating.
  • You want a durable, long-term investment with high efficiency.
  • You already have radiators or underfloor heating installed.

Choose a Water Heater If:

  • You only need hot water for daily use, not space heating.
  • You live in a mild or warm climate.
  • You prefer lower upfront costs and simple installation.

If you need both space heating and hot water, consider a combi boiler — a hybrid system that heats both your home and water in one compact unit.

Maintenance and Longevity Tips

Both systems perform best with regular care.

For Hot Water Boilers:

  • Schedule annual inspections to clean burners, check pressure, and test safety valves.
  • Maintain proper water levels and eliminate air in the pipes.
  • Treat boiler water to prevent corrosion and scale buildup.

For Water Heaters:

  • Drain the tank annually to remove sediment.
  • Inspect and replace the anode rod every 3–5 years.
  • Check temperature settings (ideally around 120°F / 49°C) to balance efficiency and safety.

Pros and Cons Summary

System Pros Cons
Hot Water Boiler High efficiency, long lifespan, ideal for whole-house heating Higher installation cost, requires regular service
Water Heater Affordable, compact, easy to install Lower efficiency, shorter lifespan, only for domestic water

Conclusion

Understanding the difference between a hot water boiler and a water heater helps you make smarter, more energy-efficient decisions.

If your priority is home heating, a boiler is the best option — durable, efficient, and reliable. If your main need is hot water for household use, then a water heater (tank or tankless) will suit you better. For many homeowners, the right solution may even be a combi system, offering both functions in one compact unit.

Before purchasing, always consult a licensed HVAC professional to evaluate your space, heating load, and budget — ensuring your system runs efficiently and safely for years to come.

Pure Steam Boilers: The Core Engine of Industrial Clean Power

I. Definition and Core Value of Pure Steam Boilers

Pure steam boilers are specialized equipment designed for high-purity industries such as pharmaceuticals, food processing, and biotechnology. Their core function is to precisely control the steam generation process to produce steam that is free of impurities, low ions, and microbial contamination, meeting international standards (such as ISO 8573-1 and EN 285). Compared to traditional industrial steam boilers, pure steam boilers adhere to higher standards in structural design, material selection, and operational control, ensuring steam quality that meets medical-grade or ultrapure water standards. For example, after adopting pure steam boilers, a pharmaceutical company reduced the microbial contamination rate in its sterilization process from 0.3% to 0.001%, and its product qualification rate increased by 12%.

II. Technical Principles and Core Components

1. Dual Purification System
The pure steam boiler achieves steam cleanliness control through two stages of purification:

Primary purification (evaporation section): Utilizes a 316L stainless steel evaporator, coupled with a multi-stage water treatment system (such as reverse osmosis + EDI), to control the inlet water conductivity to ≤1μS/cm, ensuring initial steam purity.
Secondary purification (separation section): A high-efficiency steam-water separator (separation efficiency ≥99.9%) and a 0.2μm PTFE filter element intercept tiny droplets and particulates carried in the steam. Tests conducted by a biological laboratory showed that after secondary purification, the non-volatile residue (NVR) content in the steam was reduced from 12mg/L to 0.03mg/L.
2. Fully Enclosed Piping Design
The pure steam boiler utilizes seamless 316L stainless steel piping, equipped with an automated argon arc welding process. The welds are 100% radiographically inspected. Sanitary clamps are used for piping connections to minimize dead spots and the risk of microbial growth. For example, after a vaccine manufacturer adopted a fully enclosed pipeline, the secondary contamination rate during steam transportation dropped from 0.8% to 0.02%.

3. Intelligent Control System
The pure steam boiler integrates a PLC+HMI intelligent control system, enabling real-time monitoring of steam temperature (accuracy ±0.5°C), pressure (accuracy ±0.01 MPa), and conductivity (accuracy ±0.1 μS/cm). When steam quality exceeds standards, the system automatically triggers an alarm and initiates an emergency purification procedure. After implementing this system, a semiconductor company reduced its equipment failure rate by 65% ​​and annual maintenance costs by 280,000 yuan.

III. Core Advantages and Industry Applications

1. Pharmaceutical Industry: Sterility Assurance
In injectable drug production, the pure steam boiler provides FDA-compliant steam to sterilizers, ensuring sterilization temperature uniformity (±1°C) and precise sterilization time. Statistics from a multinational pharmaceutical company show that adopting pure steam has increased the product sterility test pass rate from 99.2% to 99.98%, reducing annual recall losses by 12 million yuan.

2. Food Industry: Flavor Preservation
During the dairy product sterilization process, pure steam boilers can output steam with a low oxygen content (oxygen content ≤ 0.1 ppm), preventing flavor degradation caused by oxidation of milk proteins. Tests conducted by one dairy company showed that using pure steam extended product shelf life by 30% and reduced consumer complaints by 42%.

3. Electronics Industry: Ultrapure Processing
During the semiconductor wafer cleaning process, pure steam boilers must provide steam that meets stringent standards of total organic carbon (TOC) ≤ 10 ppb and particulate matter (≥ 0.1 μm) ≤ 10 particles/L. After using this technology at one chip manufacturer, wafer yield increased from 89% to 94%, reducing the cost per wafer by $18.

IV. Key Points for Selection and Compliance

1. Material Certification
Preferably, 316L stainless steel certified to the ASME BPE standard is selected to ensure corrosion resistance and hygienic properties. A medical device company suffered annual losses of 500,000 yuan due to rust in steam pipes caused by substandard materials.

2. Purification Efficiency
Pay attention to the separation efficiency of the steam-water separator (required to be ≥99.5%) and the filter replacement cycle (recommended ≤2000 hours). A biopharmaceutical company received an FDA warning due to untimely filter replacement, which resulted in excessive steam microbial contamination.

3. Compliance Documentation
Suppliers should be required to provide complete DQ (Design Qualification), IQ (Installation Qualification), and OQ (Operational Qualification) documentation, complying with GMP, cGMP, and other regulatory requirements. An exporting company had its goods detained by EU customs due to missing documentation, resulting in losses exceeding 3 million yuan.

V. Future Trends: Modularity and Intelligence

1. Modular Design
Use standardized modules (such as evaporation modules, purification modules, and control modules) to enable rapid installation and expansion. A hospital shortened the construction period from six months to two months when building a new pharmaceutical preparation workshop through modular integration.

2. AI Predictive Maintenance
Integrated machine learning algorithms analyze operational data to predict faults such as filter life and pipeline corrosion. A chemical company, after implementing this approach, reduced equipment downtime by 75% and annual maintenance costs by 40%.

3. Green Energy Coupling
Explore coupled systems combining photovoltaics with electric-heated pure steam boilers or biomass gasification with gas boilers to reduce carbon emissions. A food factory implemented a photovoltaic coupling solution, reducing annual CO2 emissions by 1,200 tons and receiving a government subsidy of 800,000 yuan.

Conclusion: Pure steam boilers have become the "invisible guardians" of the high-cleanliness industry, and their technological advancements are evolving from single-device optimization to systemic solutions. For businesses, selecting a supplier with full lifecycle service capabilities is key to achieving compliant production and reducing costs and increasing efficiency.

Industrial Boiler Size Guide: How to Select the Right Capacity for Your Application

Choosing the right boiler size is one of the most important decisions in any industrial heating system. A properly sized boiler not only ensures steady production and energy efficiency, but also helps reduce long-term operational costs. Selecting a boiler that is too large or too small can lead to wasted fuel, unstable operation, and even premature equipment failure.

What Does Boiler Size Mean?

In industrial applications, the term “boiler size” refers to the unit's capacity to generate heat or steam. It is usually measured in tons of steam per hour (TPH), kilowatts (kW), or British Thermal Units (BTU). For example, a 1-ton steam boiler can typically produce around 700 kW of heat output per hour.

Different types of boilers express capacity differently. A steam boiler focuses on steam generation rate (kg/h or ton/h), while a hot water boiler is rated by its total heat output. Understanding this distinction is the first step toward proper sizing.

boiler size

Why Correct Boiler Sizing Matters

Boiler sizing is not only a technical requirement but also an economic one. A boiler that is oversized will cycle on and off frequently, reducing efficiency and increasing wear. On the other hand, an undersized boiler cannot meet process demands, leading to production delays or system stress. The right size ensures:

  • High Efficiency: The boiler operates in its optimal range with minimal fuel waste.
  • Stable Operation: Steady steam or hot water supply supports continuous production.
  • Cost Savings: Proper sizing reduces energy bills and maintenance expenses.
  • Safety and Compliance: Correct pressure and capacity help meet industrial safety standards.

Key Factors Affecting Boiler Size Selection

1. Steam or Hot Water Demand

The most important factor in determining boiler size is your actual demand. Calculate the total heat load required for your process or building. For steam systems, this is often measured in kg/h or ton/h of steam. For hot water systems, calculate in kW or BTU/h.

2. Type of Fuel Used

Fuel type affects combustion efficiency. For example, natural gas boilers often have higher efficiency than biomass or diesel boilers, meaning a slightly smaller unit may deliver the same output.

3. Operating Pressure and Temperature

Higher pressure and temperature requirements demand greater boiler capacity. In power generation or chemical industries, boilers may operate at pressures exceeding 2 MPa, while food processing systems require lower ranges.

4. Industry Application

Different industries have different steam or heat requirements. For example, a textile factory needs continuous, medium-pressure steam, while a chemical plant may need high-pressure steam for reactors and dryers.

5. Future Expansion

If your facility plans to expand, it's wise to include an extra 10–20% capacity. Alternatively, consider modular systems with multiple boilers that can run individually or together as demand changes.
gas steam boiler

How to Calculate the Required Boiler Size

Here's a simple step-by-step method to estimate boiler capacity:

  1. Step 1: Calculate the total heat load (kcal/h, kW, or BTU/h) required by your process or building.
  2. Step 2: Convert the load into steam or hot water capacity based on fuel type and efficiency.
  3. Step 3: Add a 10–20% margin to ensure consistent performance during peak demand.
Application Steam Demand (kg/h) Suggested Boiler Size (ton/h)
Food Factory 2,000 2 ton/h
Textile Plant 5,000 5 ton/h
Chemical Plant 10,000 10 ton/h

10 ton steam boiler

Common Mistakes in Boiler Sizing

  • Oversizing: Many buyers assume a bigger boiler is safer, but this leads to inefficiency and fuel waste.
  • Ignoring Load Variations: Boilers must handle both base and peak loads efficiently.
  • No Allowance for Maintenance: Always plan for backup capacity during maintenance shutdowns.
  • Lack of Professional Assessment: Consulting with boiler manufacturers or engineers ensures accurate sizing and safety compliance.

Case Study: Optimizing Boiler Capacity for a Textile Factory

A textile manufacturer in Southeast Asia once operated a 10-ton gas boiler that frequently ran below 50% capacity. After a professional evaluation, the company replaced it with an 8-ton high-efficiency condensing boiler. The new system not only met full production demand but also reduced fuel consumption by 15% and maintenance costs by 20% annually.

Conclusion

Choosing the right industrial boiler size is essential for achieving efficiency, reliability, and cost-effectiveness. A properly sized boiler supports smooth production, saves energy, and ensures long-term equipment health. Always consider your process demand, pressure, fuel type, and future plans before purchasing. For the best results, consult an experienced boiler manufacturer to design a system tailored to your specific application. Whatsapp: +8613838529852

Steam boiler performance is a measure of how effectively a boiler converts fuel energy into useful steam. Key performance indicators include fuel-to-steam ratio, steam quality, stack temperature, and stability under load. Several factors influence performance: fuel quality, water chemistry, load profile, combustion control, and maintenance practices.

Key Factors That Affect Performance

  • Fuel quality — Poor fuel increases deposits and decreases combustion efficiency.
  • Water quality — Scale and corrosion reduce heat transfer and cause failures.
  • Boiler load — Frequent low-load operation or cycling lowers efficiency.
  • Combustion settings — Incorrect air–fuel ratio leads to wasted fuel.
  • Maintenance frequency — Neglect accelerates deterioration and energy loss.

Common Problems That Reduce Boiler Efficiency

Before optimizing, identify the usual suspects that degrade steam boiler performance:

Scale and Soot Buildup

Deposits on heat transfer surfaces act as insulation and force higher fuel use to achieve the same steam output.

Corrosion and Poor Water Chemistry

Oxygen, carbon dioxide and aggressive pH can corrode tubes and drums, causing leaks and heat transfer loss.

Leaky Steam Traps and Valves

Steam leaks waste energy and lower available pressure for processes and heating.

Inadequate Insulation

Uninsulated piping and vessel surfaces dissipate heat to the environment rather than delivering useful energy.

Poor Combustion Control

An improper air–fuel mixture leads to incomplete combustion, higher flue temperatures and increased fuel consumption.

Expert Maintenance Tips to Improve Steam Boiler Performance

Implement the following expert recommendations to boost performance and reliability.

1. Maintain Proper Water Treatment

Effective water treatment prevents scale, corrosion and foaming—major causes of degraded performance. Use softeners, deaerators and chemical dosing tailored to your feedwater source. Regularly test pH, conductivity, hardness and dissolved oxygen.

2. Schedule Routine Cleaning and Inspections

Remove soot and scale from tubes and heat surfaces on a scheduled basis. Inspect burners, safety valves, gaskets and refractory. Early detection of wear or deposits prevents efficiency loss and unplanned outages.

3. Optimize Combustion Settings

Tune burners and balance air supply to achieve complete combustion. Use oxygen trim systems or stack gas analyzers to monitor excess oxygen and CO levels and adjust the air–fuel ratio for lowest fuel use and emissions.

4. Improve Steam and Condensate Management

Repair leaking traps and valves, and maximize condensate return. Reusing hot condensate reduces makeup water and preheats feedwater, cutting fuel demand.

5. Insulate Piping and Boiler Surfaces

Quality insulation reduces radiant and conductive heat loss. Inspect insulation regularly for damage and moisture ingress, replacing or repairing as needed.

6. Implement Preventive and Predictive Maintenance

Use a preventive schedule for blowdown, filter replacement, and component checks. Deploy predictive tools—vibration sensors, thermography, and IoT monitoring—to catch deviations before they cause inefficiency.

Upgrades and System Improvements

Consider capital improvements that deliver measurable efficiency gains:

  • Economizers — Recover flue gas heat to preheat feedwater.
  • Variable Speed Drives (VSD) — Match pump and fan speeds to load, reducing electrical and fuel use.
  • Modern Control Systems — Advanced automation keeps combustion and load control within optimal ranges.
  • Condensate Recovery — Capture and reuse condensate to save water and energy.

Measuring and Tracking Performance

Track relevant KPIs to quantify improvements and find new opportunities:

  • Fuel-to-steam ratio (kg fuel per tonne steam)
  • Stack temperature (indicates heat loss)
  • Blowdown rate (affects water chemistry and loss)
  • Steam pressure and quality

Use data logging and periodic energy audits to benchmark and validate upgrades or maintenance actions.

Environmental and Cost Benefits

Improved steam boiler performance reduces CO₂ emissions and operating costs. Efficient boilers consume less fuel, lower maintenance expense, and contribute to corporate sustainability goals and regulatory compliance.

Practical Implementation Tips

  • Start with a baseline energy audit to identify the biggest losses.
  • Create a prioritized action list: quick wins (trap repairs, insulation) vs. long-term investments (economizers, control upgrades).
  • Train operators on best practices and encourage consistent record-keeping.
  • Engage qualified service providers for specialized tasks (combustion tuning, water treatment design).

Conclusion

Boosting steam boiler performance requires a combination of proper water treatment, regular cleaning, combustion optimization, and targeted system upgrades. A disciplined maintenance program—including preventive and predictive activities—yields reliable steam, lower fuel use, and longer equipment life. For industrial facilities, investing in boiler performance is a high-return strategy that pays off in reduced costs and improved sustainability.

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.

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.
