Filed: 1985-06-27
Abstract: PURPOSE:To enable to detect gas flames and leakage of gas, by providing a piece of thermoelectric element which can detect gas flames and flow of gas in the neighborhood of a burner in distinction from each other. CONSTITUTION:When combustion takes place in gas, a thermoelectric element 3 detects the temperature T1 in thermo-sensing points 3a and the temperature T2 in cold contacting points 3b, and a plus minus determining means 4 determines DELTAT=T1-T2>0. When the gas is not burned on a burner 1, the temperature in the thermo-sensing points 3a is lowered, and the plus minus determining means 4 determines DELTAT<0. A logic circuit 5 confirms the presence of flames when a flame presence determining means 6 determines the presence of flames, and the means 4 determines DELTAT>0. To the contrary, the circuit 5 determines the leakage of gas when the means 4 determines DELTAT<0. On the other hand, it determines that a gas detecting system is abnormal when the means 6 determines the absence of flames and the means 4 determines DELTAt>0. To the contrary, when the means 4 determines DELTAT<0, the logic circuit 5 determines leakage of gas.
