1. According to the structure of the boiler can be divided into boiler (fire tube boiler), water boiler and water tube fire boiler.

2. According to different uses can be divided into power plant boilers, industrial boilers, boilers and other life.

3 according to the size of the capacity can be divided into large boilers, medium-sized boilers and small boilers. Traditionally, boilers with evaporation greater than 100 t / h are large boilers, boilers with 20-100 t / h evaporation are medium boilers and boilers with less than 20 t / h evaporation are small

Boiler.

4. According to the size of steam pressure can be divided into low pressure boiler (p≤2.5MPa), medium pressure boiler (2.5MP

5. By fuel and energy types can be divided into coal-fired boilers, oil-fired boilers, gas boilers, waste heat (waste heat) boilers.

6. By fuel combustion in the boiler can be divided into layer burner, boiling furnace, room burner.

7. According to the working fluid in the evaporation system can be divided into natural circulation circulation boiler, forced circulation boiler, boiler and so on.
