Abstract

PURPOSE:To actuate the thermocouple type safety valve stably and surely by a method wherein the thermocouple is arranged between a catalyzer burner and a wire net and the zero junction of the thermocouple is provided at the lower part of the burner through a radiating plate which is a separate part from a burner box. CONSTITUTION:With the operation of an operating knob 2, the gas fed from a gas inlet 1 is burnt at a heating burner 16 and a catalyzer burner 6. After the heating burner 16 goes out, the catalyzer burner 6 burns with the supply of the secondary air (indicated with the arrows A) and discharges the exhaust gas as indicated with the arrow B. At that time, the flow of the secondary air and the exhaust gas causes the draft effect to flow the cold air as indicated with the arrow C. Because the zero junction of the thermocouple 8 is affixed within the cold air flow through the radiating plate, thermal electromotive force generated in the thermocouple 8 is stable and consequently holds the safety valve 3 stably to bring to the stationary operation.
