Y5-47 series boiler centrifugal induced draft fan is designed for 1-20 t/h industrial boilers burning various coals and equipped with smoke suppression and dust removal devices. It can be selected for those with similar air inlet conditions and performance. The maximum temperature shall not exceed 250 ℃. A dedusting device with a dedusting efficiency of not less than 85% must be added in front of the induced draft fan to reduce the dust content of flue gas entering the fan and improve the service life of the fan.

This series of induced draft fan adopts two transmission modes: coupling direct transmission (D type) and V-belt transmission (C type). Except that the induced draft fan equipped with a 20t boiler needs a large power, which is driven directly by coupling (D type), the others are driven by V-belt (C type). The C-type drive can not only meet the requirements of configuring all kinds of dust collectors for boilers of the same tonnage with one machine number and different rotating speeds, reducing the fan series and machine numbers, but also facilitate the use of units according to the actual conditions of the current industrial boiler series, great differences in the quality of coal used, different resistance of dust collectors used, and large differences in the air volume and air pressure of the required induced draft fans, Automatically change the spindle speed to obtain the desired air volume and air pressure.
