Abstract

641,846. Burner apparatus. COMBUSTION ENGINEERING-SUPERHEATER, Inc. April 27, 1948, No. 11548. Convention date, Dec. 2, 1947. [Class 75(i)] [Also in Group XII] The combustion chamber 10 of a burner fired boiler has a bypass flue 13 with a thermally responsive element 15 made of an alloy having a high negative coefficient of electrical resistivity with respect to temperature connected in series with a relay 16 to a source of electric power, the switch element 20 of said relay being arranged in the circuit of an electromagnetic coil 31 which controls a valve 23 supplying fuel to the burner 11. The circuit includes an alarm 33 and a second thermally responsive element 27 in the flue 13 controls diluting air supplied from a fan 25. If the burner is extinguished the temperature of the element 15 drops, its electric resistance rises reducing the current flowing through and releasing the relay 16 which results in the operation of the alarm 33 the breaking of the fuel control circuit and consequent closing of the valve 23.
