ABSTRACT:
A self-energizing burner control system for a fuel burner is accomplished by heat from a pilot flame 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 is converted to a regulated direct current potential. The regulated direct current potential in turn is used to operate a solid state temperature control or controller. This controller has a sampling rate that is visually indicated by a light emitting diode when a proper voltage is present. The system further insures that a temperature sensor is in place, and is functioning properly.
