こと； を特徴とする燃焼安全装置。[Claims for Utility Model Registration] A heat-sensitive sensor that is provided facing a combustion section and converts the heat of the combustion section into an electrical signal; An amplifier that amplifies the output of the heat-sensor; Monitors the output voltage of the amplifier; emit a flame detection signal only when the amplifier output voltage is between an ignition detection level and a limiter level, and a non-combustion signal when the amplifier output voltage is less than or equal to the ignition detection level; The ignition detection level is based on the minimum temperature of the combustion section that can be considered as ignition, and the limiter level is based on the minimum temperature of the combustion section that can be considered as ignition. Each setting is based on the maximum temperature expected during normal combustion operation in the combustion safety device.
