Boiler is composed of pot and furnace, the upper part of the water holding parts for the pot, the lower part of the heating for the furnace, pot and furnace integrated design called boiler.

 

The boiler defined in the Regulations on Safety Supervision of Special Equipment refers to the equipment that uses various fuels, electricity or other energy sources to heat the liquid filled to a certain parameter and to output heat energy. The scope is defined as a pressurized steam boiler with a volume greater than or equal to 30L, a pressurized hot water boiler with an outlet water pressure greater than or equal to 0.1MPa (meter pressure) and a rated power greater than or equal to 0.1Mw, and an organic heat carrier boiler. Excerpt from the regulations on safety supervision of special equipment in People's Republic of China

 

Classification standard

 

There are many classification methods for boilers, which can be classified according to the use of boilers, the structure of boilers, the type of fuel, and the type of water circulation and pressure.

 

1. Classification according to boiler usage

 

The boiler can be used as a thermal power boiler and heating boiler. Power boilers include utility boilers, ship boilers and locomotive boilers, which are used for power generation, ship power and locomotive power. Heating boilers include steam boilers, hot water boilers, heat pipe boilers, hot air stoves and heat-carrying body heating furnaces, etc., and steam and hot water are obtained accordingly. Hot air and heat carrier.

 

2. Classification according to boiler body structure.

 

According to the boiler structure, it is mainly divided into fire tube boiler and water tube boiler. Fire tube boilers include vertical boilers and horizontal boilers, water tube boilers include horizontal water tube boilers and vertical water tube boilers.

 

3. Classification of boiler fuel types

 

According to the types of fuel used in boilers, they are coal fired boilers, oil fired boilers and gas fired boilers. The coal-fired boiler can be divided into a layer burning boiler, a room burning boiler and a boiling boiler according to the mode of combustion.

 

4. Classification according to boiler capacity

 

Small boilers with evaporation less than 20t/h and large boilers with evaporation greater than 75t/h are called small boilers. Medium boilers are called boilers with evaporation between the two.

 

5. Classification according to boiler pressure.

 

Boilers below 2.5 MPa are called low-pressure boilers, and those above 6.0 MPa are called high-pressure boilers. The pressure between them is called medium-pressure boilers. In addition, there are extra high pressure boilers, sub critical boilers and supercritical boilers.

 

6. Classification according to boiler water cycle.

 

According to the boiler water circulation form can be divided into natural circulation boiler and forced circulation boiler (including once-through boiler).

 

7. Classification by device.

 

It can be divided into fast installed boiler, assembled boiler and bulk boiler. In addition, there are wall mounted boilers, vacuum boilers and modular boilers.
