Seal Air Fans Two (2) 100% capacity, single inlet, single speed Seal Air Fans Provide seal air for the Pulverizer Roll Wheels, Yoke Seals and Coal Feeder. The air source for the fans comes from the Cold Primary Air Duct near the Pulverizers. A mechanical louvered Damper with locking mechanism regulates the amount of flow from the fans. The Damper’s position will be determined during comissioning.

Seal Air Fans One Seal Air Fan is required to be in service prior to starting the Pulverizers and subsequently the Coal Feeders. One (1) Seal Air Fan is considered as a spare and will automatically start if the Seal Air Pressure Switch indicates a low pressure situation exists. Under circumstances where six (6) Pulverizers are operating, the second Seal Air Fan will need to be started.

Seal Air Fans Swing Damper
In the common discharge duct is a mechanical Swing Damper which will automatically position itself when a fan starts. Actuation is due to the static pressure & flow created by the fan.
