Primary fan: (Take medium-speed coal mill and direct blowing pulverizing system as an example) The primary fan provides primary air, which is divided into two paths from the fan. One path passes through the air preheater and is called hot primary air. The other path does not pass through the air preheater. The device is called cold wind. Among them, the hot primary air provides drying output and ventilation output for the coal mill, which dries the pulverized coal ground by the coal mill and then carries the pulverized coal into the boiler burner. The cold primary air and the hot primary air are mixed at the entrance of the coal mill, which plays the role of adjusting the inlet/outlet temperature of the coal mill, and is also part of the ventilation output of the coal mill.

Air blower: Provides secondary air to affect the flame at the burner and cool the burner.

The induced draft fan is to extract the flue gas from the boiler and maintain the negative pressure of the boiler.

Booster fan: The wind from the induced draft fan enters the booster fan all the way and enters the chimney through the bypass. The wind from the booster fan enters the desulfurization system to desulfurize the flue gas and discharge it into the chimney.
