Fan
Fan is a mechanical machine that relies on input mechanical energy to increase gas pressure and deliver gas. It is a driven fluid machine that can be divided into FD fan and ID fan. The FD fan is operated eccentrically by the rotor biased in the cylinder, which sucks, compresses, and discharges air through volume change between blades in rotor groove . The FD fan is a device that generates negative pressure by the rotation of impeller and then extracts air from the system (equipment), which is generally installed at the end of the boiler for extracting hot flue gas in the furnace.

Precautions:

1. Pay special attention to the temperature of flue gas, if it is lower than design temperature, please control adjusting range of regulating door and pay close attention to the change of current value of the motor and ensure no overload occured to the motor.

2. When using the wet dust collector device, please adjust water intake of the dust collector. It is strictly forbidden to run the fan with sand or water in the process of operation.
