摘要： A hot wire type of gas ignition system uses a negative temperature coefficient resistor-ignitor element that is deenergized after ignition has occurred. The ignition and safety monitoring of the circuit is accomplished by a second flame detector means, and the flame responsive circuit that has been disclosed in a flame rectification circuit.

摘要： A fuel burner control system that is fail safe and which controls three fuel burner functions is provided for. The system utilizes two different digital clock means that are separated in time from one another to ensure separate gating of the fuel burner output functions. The system further uses a negative power supply with respect to the circuit ground for control purposes while energizing the output switch means with a positive potential thereby eliminating inadvertent operation in the event of circuit component failures.
