What is the composition of the natural gas steam boiler?

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.
