Abstract
A control system for an induced or forced draft combustion apparatus has a single pressure transducer for providing an electrical signal indicative of pressures by alternately responding to the fuel pressure to the combustion apparatus and the fuel pressure plus the induced draft lower suction pressure. The signal output of the transducer is connected to a controller for controlling the fuel flow to maintain a predetermined fuel/air ratio for efficient and safe combustion of the fuel in the combustion apparatus.
