<p>A self-energizing burner control system for a fuel burner (10) is accomplished by heat from a standing pilot (12) energizing a thermoelectric generator (14). The thermoelectric generator supplies power to an oscillator (20). The oscillator has an output that is stepped up (33) in voltage level and converted to a regulated direct current potential (35). The regulated direct current potential in turn is then used to operate a solid state temperature controller (45). The controller responds to a temperature at a thermistor (54) to control a field effect transistor (61) connected in series with a solenoid (64) of a fuel valve (64,65).</p> |
