Abstract
The invention is particularly applicable to combustion control apparatus for burners, having a motor-controlled fuel value, and a motor-controlled damper. Coarse control of the damper position is provided by a mechanical profiler, and a trim motor provides fine control of the damper. Overall, the air or fuel is controlled continuously by an up to the minute control signal corresponding to the instantaneous burn rate.
