摘要： A fuel burner control system including a valve for controlling the flow of fuel to a burner, a resistive heater element for igniting fuel, a power supply for supplying current to the heater element, a flame sensing circuit comprising an ac source for supplying ac voltage to the heater element, and a detector for producing an output signal only in response to the flow through the heating element of current rectified by the flame, a valve control circuit for maintaining the valve open in response to the output signal, and a coupling circuit interconnecting the heating element with both the power supply and the sensing circuit and adapted to prevent the flow of current therebetween. By utilizing a coupling circuit that prevents the flow of current between the power supply and the flame sensing circuit, the resistive heater element can be efficiently and alternately used both as a fuel igniting mechanism and as an electrode for deriving current rectified by flame at the burner.
