とを設けたことを特徴とする燃焼安全装置。[Scope of Claim for Utility Model Registration] A gas sensor that utilizes changes in the resistance of metal oxide semiconductors is installed in the flow path of exhaust gas from combustion equipment that has a burner and a heat exchanger to detect incomplete combustion. In the device, the gas sensor has an output that changes in a mountain shape depending on the heating temperature, and a maximum value of the output occurs at a specific temperature, and a resistance is connected in series to a temperature-sensitive resistor, and a first temperature compensating piece for compensating the output of the gas sensor at a temperature below the temperature at which the maximum value of the output occurs; and a resistance connected in series to the temperature-sensitive resistor, and the maximum value of the output. The heating temperature of the gas sensor is output from the resistance value of at least one temperature-sensitive resistor in the second temperature compensation piece for compensating the output of the gas sensor at a temperature higher than the temperature at which . temperature detection means for detecting whether or not the temperature is higher than the temperature at which the maximum value of
A combustion safety device characterized by being provided with.
