id and fd fan uses in coal fore

Boiler Control for Fossil-Fired Utility Boilers 3 The Air Controls provide the ability to maintain a uniform response for either one or two fan operation. In addition, bias action applied to the fans will not result in a process upset. The FD fans are not released to automatic unless at least one ID fan has been placed in automatic.
