Usage 
XH-BF-12 Centrifugal Fan blower is mainly used in 2t / h ~ 670t / h steam boiler ventilation in the thermal power plant, and it can also meet the high pressure head performance parameters of fluidized bed furnace. This series fans can also be used for dust, mine fan General ventilation system.


XH-BF-12 Centrifugal Fan blower is for 35t / h ~ 410t / h circulating fluidized bed boiler feed system, the system fan can also be used for dust, mine ventilation and general ventilation system.
The medium for the blower is air, and the medium for the draft fan is flue gas or particulate matter containing impurities. If the impurity concentration is less than 200mg / m3, the impeller can be used for more than five years. If the impurity is large, the service life is shortened and the maximum temperature of the blower can not exceed 250 ºC.

Model Series
XH-BF-12 type Centrifugal Fan have total 20 machine No. and 40 specification, from No.8D~29.5D

To make the proper fan selection, you must consider the following system conditions the fan will be subjected to:

1. What is the required airflow?
This is rated in cubic feet of air per minute (CFM) or, in metric equivalent, it is rated in cubic meters of air per hour (M³/Hr).

2. What is the static pressure through the complete system?
This is rated in static pressure water gauge (SP) or, in metric equivalent, it is rated in Pascal's (Pa).

3. What is the ambient air temperature outside the fan?

4. What will be the airflow conditions through the fan?

A.    Clean or dirty (contaminated) air?
