18 Feb 2022

The primary air fan of the boiler consists of motor, impeller, casing, air inlet box, current collector, base, regulating control system, etc.

The working process of the primary air fan: Take the medium-speed coal mill and direct-fired pulverizing system as examples, the atmosphere enters the primary air fan and is divided into two paths after being boosted by the primary air fan. One path of the atmosphere enters the primary airpipe in front of the coal mill. The other path enters the air preheater for heating, and then enters the hot primary air duct in front of the coal mill, where the hot air and cold air are mixed.
