There are many methods for classifying boilers, which can be divided according to the use of the boiler, or according to the structure of the boiler and the type of fuel, and can also be classified according to the type of water circulation and pressure. 1, according to the use of boiler classification
The boiler can be used as a thermal power boiler and a heating boiler. Power boilers include power station boilers, ship boilers, and locomotive boilers, which are used for power generation, ship power, and locomotive power. The heating boiler includes a steam boiler, a hot water boiler, a heat pipe boiler, a hot blast stove, a heating medium heating furnace, etc., and steam and hot water are accordingly obtained. Hot air and heat carrier.
2, according to the boiler body structure classification
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, and water tube boilers include cross-tube boilers and vertical-tube boilers.
3, classified by boiler fuel type
According to the types of fuel used for boilers, they are classified as upgrading technologies for coal-fired boilers, oil-fired boilers and gas-fired boilers and coal-fired boilers, and alternative products for oil and gas furnaces--pulverized coal boilers, gas-fired dual-use boilers, etc. Coal-fired boilers can be divided into stratum-fired boilers, room-fired boilers and boiling boilers according to the combustion method. The latest fuel is an alcohol-based fuel boiler, he will greatly reduce the pollution of coal-fired boilers to the atmosphere.
4, according to the boiler capacity classification
Evaporation capacity is less than 20t/h, which is called small boiler, and the evaporation capacity is more than 75t/h, which is called large-scale boiler. The evaporation capacity is between medium and medium boiler.
5, classified by boiler pressure
A 2.5MPa boiler is called a low pressure boiler, and a 6.0MPa or higher pressure boiler is called a high pressure boiler. The pressure between the two is called a medium pressure boiler. In addition, there are ultra high pressure boilers, subcritical boilers and supercritical boilers.
6, according to the boiler water cycle classification
According to the boiler water circulation form, it can be divided into natural circulation boiler and forced circulation boiler (including the direct current boiler).
7, according to the device type
It can be divided into quick-load boilers, assembled boilers and bulk boilers. In addition, there are wall-mounted boilers, vacuum boilers, and modular boilers.
