3. According to the size of capacity can be divided into large-scale boilers, medium-sized boilers and small boilers.
1. According to the structure can be divided into pot boiler (fire tube boiler), water pipe boiler and water fire tube boiler.
(P = 1.9MPa), high pressure boiler (p = 9.8MPa), ultra-high pressure boiler (p = 13.7MPa), etc., according to the size of steam pressure can be divided into low pressure boiler (p ≤ 2.5MPa), medium pressure boiler (2.5MP
2. According to the different purposes can be divided into power plant boilers, industrial boilers, life boilers and so on.
Traditionally, the boiler is larger than 100t / h for the large-scale boiler, evaporation of 20 ~ 100t / h of the boiler for medium-sized boilers, evaporation less than 20t / h boiler for small boilers.
