* Currently，there are so many kinds of boilers with much different coal characters, with dust removing devices and waste heat reusing equipments influences, and It makes the draft power not enough so as to work normally. In order to overcome lack of the draft power, positive pressure, affect the normal inflammation of the boiler, we design and manufacture varieties of Boiler Induced Draft Fans with suitable flow rates, pressure to fit for different requirements of the users.

* The main parameters of the Boiler Induced Draft Fan are flow rate, total pressure, main shaft rotation speed, inner power and inner efficiency, etc. (please see the parameter table)

* The parameters of the Forced Draft Fan are based on the gas temperatur et＝20℃, atmospheric pressure P=101325pa, the gas density p =0.74Kg/m³. The parameters of the Induced Draft Fan are based on the gas temperaturet=200℃.
