Abstract

A self-energizing burner control system for a fuel burner is accomplished by heat from a standing pilot energizing a thermoelectric generator. The thermoelectric generator supplies power to an oscillator. The oscillator has an output that is stepped up in voltage level and converted to a regulated direct current potential. The regulated direct current potential in turn is then used to operate a solid state temperature control or controller. The controller in turn responds to a temperature at a thermistor to control a field effect transistor and series connected solenoid of a fuel valve.
