Abstract
A combustion apparatus has an exhaust system, a fuel-supply system, and an air-supply system. The ratio of fuel-to-air supplied to the apparatus is adjustable in either direction in response to control information. A temperature signal is developed which has a value proportional to the combustion-produced temperature. A first sample of that temperature signal selected during a first time interval is compared with a second sample of the temperature signal developed during a later time interval. The comparison serves to produce the control information that causes adjustment of the fuel-to-air ratio in the direction seeking a maximum of combustion-produced temperature. Digital logic circuitry is specifically utilized for the purpose of producing the desired control information.
