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.
Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.
