Coal dust
|
According to the purpose, the coal dust exhausting fan can be divided into two kinds. One, pulverized coal storage bin type exhausting fan. It blows pulverized coal from side into furnace. The coal dust do not go through the fan, so the fan pressure needs to be much high.

Gas recirculating fan
|
Centrifugal fan
|
Boiler fume
|
This model fan exhausts high temperature boiler fume, so the material and structure should be heat resistant.
