Section 23 09 11 - INSTRUMENTATION AND CONTROL FOR BOILER P…
An improved combustion control system for a combustion apparatus such as a boiler or the like controlled by a jackshaft system utilizes the load index signal output of the jackshaft system to effect trim control of the air fuel ratio of the combustion process. A linkage biasing mechanism is operably associated with the intermediate linkage

In the past, boiler pressure has been controlled with a simple proportional control which determines the firing rate (FR) for that particular burner. This can be expressed by the equation of ##EQU1## Where the firing rate is defined as between 0 and +1, P Hi is the upper pressure setpoint for the control of the boiler, and P Lo is the lower pressure setpoint for the boiler.
