Boilers can be classified in different ways.

Boilers can be divided into industrial boilers, power station boilers, Marine boilers and locomotive boilers.

According to the boiler outlet pressure can be divided into low pressure, medium pressure, high pressure, ultra-high pressure, sub-critical pressure, supercritical pressure and other boilers.


The current series of power station boilers in China are: medium pressure 3.9 mpa;

High pressure 10 mpa;

Uhv 14 Mpa;

Subcritical pressure of 17 mpa.

The current series of Industrial boilers in China are 0.5 mpa, 0.8 mpa, 1.3 mpa, 2.5 mpa.

Boilers can be divided into fire-tube boilers, fire-tube boilers and water-tube boilers according to the flow path of water and flue gas.

According to the circulation mode, it can be divided into natural circulation boiler, auxiliary circulation boiler (i.e. forced circulation boiler), direct current boiler and compound circulation boiler.

Composite circulation boilers are composed of auxiliary circulation boilers and direct current boilers, including low-cycle boilers (see power station boilers).

According to the mode of combustion boiler is divided into chamber combustion furnace, layer combustion furnace and rimming furnace.
