Application and Features of Rotary Airlock Valves

GF Rotary Airlock Valves/Pneumatic Feeder is the main equipment for supplying fuel to the boiler in the silo-type pulverizing system of thermal power plants. It is used to continuously and evenly send pulverized coal into the primary air duct and blow it into the boiler for combustion.

Rotary Airlock Valves/Pneumatic Feeder adjusts the amount of powder to control the temperature and pressure of the boiler, so as to ensure the required boiler output.

The output of the Rotary Airlock Valves/Pneumatic Feeders is determined according to a certain volumetric proportion.
