According to the boiler water cycle can be divided into natural circulation boiler and forced circulation boiler (including the boiler
In addition, there are ultra-high pressure boilers, subcritical boilers and supercritical boilers.
2.5MPa below the boiler called low-pressure boiler, 6.0MPa or more known as the high-pressure boiler, the pressure between the two known as the pressure boiler.
Evaporation of less than 20t / h known as small boilers, evaporation is greater than 75t / h known as large-scale boilers, evaporation between the two known as the medium-sized boiler.
