The boiler mainly consist of the boiler body, safety accessories, and auxiliary equipment. The main boiler part in the boiler, such as the furnace, drum, burner, water-cooled wall, superheater, economizer, air preheater, framework, and furnace wall, constitute the core part of steam production, which is called the boiler body.

1. Furnace: Ensure that the boiler fuel is burned out and the outlet flue gas temperature is cooled to a value that allows safe operation of the convective heating surface;
3. Drum: Connect the heating surfaces of the boiler together and form a water circulation circuit with the water-cooled wall, downcomer, etc. The drum stores steam and water, which can adapt to load changes. There is a steam and water separation device inside to ensure the quality of steam and water, and there is no drum in the once-through boiler.
4. Water wall panel: The main radiating heating surface of a boiler, which absorbs furnace radiation heat, heats up working fluids, and protects furnace walls.
5. Combustion equipment: Sends fuel and combustion air into the furnace to ensure stable ignition and good combustion of the fuel;
6. Air preheater: Heating the air used for fuel to enhance ignition and combustion; Absorb waste heat from flue gas, reduce exhaust temperature, and improve boiler efficiency.
2. Economizer: uses the heat from the flue gas at the tail of the boiler to heat the water supply, reducing the exhaust temperature and saving fuel.
7. Furnace wall: It is the protective shell of the boiler, serving as a seal and insulation. The heavy-duty furnace wall of a small boiler can also serve as a support for boiler components.
8. Framework: Support and fix boiler components.
