Burner control system using a radiation operated relay means
Abstract
Abstract A SUBSTANTIALLY ALL SOLID STATE CONTROL SYSTEM WHICH IS ADAPTED TO BE CONNECTED TO CONTROL A FUEL BURNER IS DISCLOSED AND PROVIDES A DELAYED FUEL AND POST-IGNITION TIMING PERIOD USING A HEATER OPERATED BIMETAL SWITCH. THE SYSTEM IS ADAPTED TO BE ENERGIZED THROUGH A LINE VOLTAGE THERMOSTAT TO PROVIDE POWER TO A FUEL BURNER MEANS WHICH MAY INCLUDE TWO STAGES OF FUEL CONTROL, ALONG WITH AN IGNITION MEANS AND FLAME DETECTION MEANS. THE SYSTEM INCLUDES A MAIN CIRCUIT MEANS HAVING TRIACS FOR CONTROL, AND FOR OPERATION OF THE VALVES THAT SUPPLY FUEL TO THE FUEL BURNER MEANS. THE SWITCHING BETWEEN THE TRIAC STAGES IS ACCOMPLISHED BY A RADIATION OPERATED RELAY MEANS WHICH INCLUDES TWO RADIATION SOURCES AND A RADIATION RESPONSIVE MEANS. THE RADIATION OPERATED RELAY MEANS PROVIDES A SOLID STATE SUBSTITUTION FOR A MORE CONVENTIONAL TYPE OF RELAY.
