At present, there are mainly two types of heating methods. One is to use a radiator to warm, and the other is to use a gas boiler to drive the central air conditioner to warm. Depending on the heating method, it is flexible to determine whether the gas boiler needs to increase the plate heat exchanger.

If you use a radiator to warm, then you do not need to add a plate heat exchanger, because the hot water boiler is directly connected to the heating system, and then the circulation between the gas boiler and the pipe network system. The amount of hot water in this part is stable and there is no need to add a plate heat exchanger.

If a gas-fired hot water boiler is used to drive the central air conditioner for heating, a plate heat exchanger must be added in the middle. Because the central air-conditioning water consumption is very large, the hot water circulation in the hot water boiler and the central air-conditioning system must be The water circulation inside should be separated. If the plate heat exchanger is not added, the boiler cannot output the heat consumed for heating.

1. Make sure there is no liquid or flammable material next to the boiler.

2. Ensure that the circuit is connected correctly and the ground wire is well connected to the grounding system.

3. Turn on the gas switch and check if the connection is stable, including the burner.

4. Ensure that the boiler setting is suitable for the gas type.

5. Check if the flue gas pipe is properly installed and unobstructed.

6. Make sure all shutoff valves are open.

7. Make sure the system is filled with water and completely drained.

8. Check if the circulation pump is turned on.

9. Purify the system by venting the air in the gas pipeline through the pressure discharge valve of the gas valve port.

10. The installer must provide the boiler operation instructions to the user and forward the installation manual to the user.

The burner can be said to be one of the most important auxiliary equipment on the gas boiler. Similarly, the installation and commissioning of the burner is one of the important steps in the boiler installation. Before installing and debugging the burner, you need to pay attention to the following points:

1. All connections are made correctly;

2. The valve on the gas supply line has been opened;

3. The gas supply is normal;

4. The setting value of the control device is correct;

5. The burner can get enough air to ensure the combustion effect;

6. The boiler and its auxiliary machines are in normal working condition;

Only after the 6-point inspection is up to standard can the burner be installed and commissioned to ensure its safety and high efficiency.

First, we need to understand the specific benefits that this steam-water separation unit can bring to steam boilers.
       1. It can avoid the local load increase of the evaporation surface of the drum and the steam space, so that the steam can be uniformly discharged out of the water surface and taken out.
       2. Can effectively weaken the kinetic energy of the steam-water mixture entering the drum, and mitigate its impact on the water surface.
       3. Make the steam-water mixture have a flow path that is sharply turned and multi-folded to make full use of the separation of centrifugal and inertia. In addition, care should be taken to guide the separated water away from being carried by the steam again. Finally, there is a large amount of surface area in order to adhere more water droplets.

At this stage, there are many types of steam separators, which can be divided into natural separation and mechanical separation according to their principles. The principle of natural separation is to take advantage of the difference in soda water density and gravity. The principle of mechanical separation relies on inertial forces, centrifugal forces and adhesion. The steam-water separation device often used in steam boilers includes underwater orifice plates, baffles, uniform orifice plates, gas collection pipes, volute separators, corrugated plates and wire mesh separators.

1. The design of the boiler should be reasonable. The furnace, combustion chamber, pipeline construction and connection must be designed and installed by professional boiler technicians. Avoid wasting heat to the boiler due to unreasonable structural design.

2. The pipeline connection of the boiler should be regularly checked regularly. If there is a leak, the furnace should be shut down immediately to prevent gas leakage and harm the safety of equipment and operators.

3. Nowadays, many gas-fired boilers have added condensing technology to recycle a large amount of latent heat in high-temperature flue gas, and then collect the recycled hot water and reuse it, which is a method to improve the combustion efficiency of the boiler.

1. Burner maintenance method
       Thoroughly clean the rotor cup, ignition, filter, oil pump, motor and impeller system of the gas boiler burner, add lubricant to the damper linkage; and re-test the combustion of the fuel.

2. Controller maintenance method
       Inspection and inspection of electrical components, control of the line, cleaning control box ash, each control point for testing. Finally, the sealing process is carried out mainly to prevent the controller components from getting wet.

3. Water supply system maintenance method
       Overhaul the water treatment device to check whether the water quality is up to standard, comprehensively clean the water treatment system, check the operation of the feed pump and the lift, and check whether the valves of each pipeline can be used flexibly. Close the valve after the water is cut off and the system is filled with water.

4. Furnace body maintenance method
       Furnace maintenance mainly includes inspection of the operating environment inside and outside the furnace and the appearance of the furnace. The working environment of the boiler must be kept dry and ventilated, and it should not be in a humid environment to prevent corrosion during long-term operation.

1. Air-inducing equipment: The flue gas generated in the operation of the boiler is sent to the atmosphere through an induced draft fan and a chimney.

2. Dust removal equipment: remove fly ash from boiler flue gas.

3. Fuel supply equipment: storage and transportation of fuel functions.

4. Water supply equipment: The feed water treated by the water treatment equipment is sent to the boiler by the feed water pump.

5. Air supply equipment: The air heated by the air preheater is sent to the furnace and the coal grinding device by a blower.

6. Automatic control equipment: automatic detection, program control, automatic protection and automatic adjustment.

1. Furnace: A value that ensures that the boiler fuel is burned out and the outlet flue gas temperature is cooled to a safe working condition on the convective heating surface.

2. Drum: The heating surfaces of the boiler are connected together and form a water circulation loop with the water cooling wall and the descending pipe. The drum is stored in soda water, which can adapt to load changes. There is a steam-water separation device inside to ensure the quality of the steam and water. The DC boiler has no drum.

3. Water wall: the main radiation heating surface of the boiler, absorb the radiant heat of the furnace, heat the working medium, protect the furnace wall and so on.

4. Combustion equipment: The fuel and the air required for combustion are sent to the furnace and the fuel is ignited and burned well.

5. Air preheater: heat the air for fuel to enhance ignition and combustion; absorb residual heat of flue gas, reduce exhaust gas temperature, and improve boiler efficiency.

6. Furnace wall: is the protective casing of the boiler, sealing and heat preservation. Heavy-duty furnace walls for small boilers can also function as support for boiler components.

7. Frame: Support and fix boiler components.
