According to the purpose, it can be divided into thermal power boiler and heating boiler.
Boiler classification:
1. Classification by boiler use
Divided into thermal power boiler and heating boiler. Power boilers include power station boilers, ship boilers and locomotive boilers, etc., and are used for power generation, ship power and locomotive power. Heating boilers include steam boilers, hot water boilers, heat pipe boilers, hot blast stoves, and heating medium heating furnaces, etc., and steam and hot water are obtained accordingly. Hot air and heating medium.
2.Classification by boiler body structure
It is mainly divided into industrial fire tube boilers and industrial water tube boilers. Fire tube boilers include vertical boilers and horizontal boilers, and water tube boilers include horizontal water tube boilers and vertical water tube boilers.
3. Classified by the type of boiler fuel
It is divided into coal-fired industrial boilers, oil-fired industrial boilers and gas-fired industrial boilers, pulverized coal industrial boilers, and gas dual-use boilers. Coal-fired boilers can be divided into stratified-fired boilers, room-fired boilers and boiling boilers according to their combustion methods.
4.Classification by boiler capacity
Those with evaporation less than 20t / h are called small boilers, those with evaporation greater than 75t / h are called large boilers, and those with evaporation between the two are called medium-sized boilers.
5. Classified by boiler pressure
Boilers below 2.5 MPa are referred to as low pressure boilers, those above 6.0 MPa are referred to as high pressure boilers, and pressures between the two are referred to as medium pressure boilers. In addition, there are ultra-high pressure boilers, subcritical boilers and supercritical boilers.
6.Classification by boiler water circulation form
Divided into natural circulation boiler and forced circulation boiler (including once-through boiler).
7. Classified by device form
Divided into quick-installed boilers, assembled boilers and bulk boilers. In addition, there are forms such as wall-mounted boilers, vacuum boilers and modular boilers.
