The classified method of boiler is very much, can according to the purpose of the boiler, can also according to the boiler structure, fuel species, may be classified according to the form of the water cycle, pressure.
Classification of boiler USES
Boilers can be used as thermal power boilers and heating boilers. Power boilers include power plant boilers, ship boilers and locomotive boilers for power generation, ship power and locomotive power. Heating boilers include steam boilers, hot water boilers, heat tube boilers, hot blast furnaces, and hot heating furnaces, and they get steam and hot water accordingly. Heat and heat, etc.
2, according to boiler body structure classification
The boiler structure is divided into fire tube boiler and water tube boiler. Fire tube boilers include vertical boilers and horizontal boilers, and water tube boilers, including water tube boilers and vertical tube boilers.
Classify the fuel types according to the boiler
According to the boiler fuel types classified as coal-fired boiler and oil-fired boiler and gas boiler and coal fired boiler to upgrade technology, oil and gas furnace alternatives - pulverized coal fired boiler, gas boiler etc. Coal-fired boilers can be divided into floor combustion boilers, chamber fire boilers and boilers. The latest fuel is an alcohol-based fuel boiler, which will greatly reduce the environmental pollution of coal-fired boilers.
4, according to boiler capacity classification
The amount of evaporation less than 20t/h is called a small boiler, and the amount of evaporation is greater than 75t/h, which is called a large boiler, and the amount of evaporation in between is called a medium boiler.
Type according to boiler pressure
The boiler under 2.5 MPa is called low pressure boiler, and above 6.0 MPa is called high pressure boiler. In addition, there are ultra high pressure boilers, subcritical boilers and supercritical boilers.
According to boiler water circulation
The boiler water circulation can be divided into the natural circulation boiler and the forced circulation boiler (including the dc boiler).
Classify by device form
It can be divided into fast boiler, assembly boiler and bulk boiler. There are also wall boilers, vacuum boilers and boilers.
