Conveying of pulverized coal of thermal power plant boiler combustion system, mainly adopt centrifugal fan/blower.
Coal Powder fan/blower could be divided into 2 type:
1. Storage Coal Powder fan/blower, it is blowing coal to the inside of the boiler,powder is not directly through the fan,
need high exhaust pressure;
2.Straight type Powder fan/blower, it blowing powder to furnace directly. As the powder worn wheel 
and the body shell, so the wear-resisting material should be adopted.
