ABSTRACT:
A method and apparatus for applying exhaust gas analysis to simple combustion control systems wherein the fuel flow and air flow control devices are interconnected with fixed mechanical linkage, or interconnected by a single specific signal, between the fuel flow and air flow control devices. An apparatus and method are disclosed to automatically compensate the air-to-fuel ratio, pre-calibrated on a volume basis, for uncontrolled variations of air or fuel quality such as density, BTU content and the like so that the calibration of the rate of combustion air flow relative to the rate of fuel flow will always be substantially correct even while these flow rates are changing.
