燃焼装置の自動停止装置。 It has a plurality of burners, a plurality of solenoid valves interposed in parallel in gas passages to these burners, and a combustion control means that outputs a control signal to a relay drive circuit that drives a relay that opens and closes the solenoid valves, In a combustion device in which the number of burners to be burned is switched by opening and closing a solenoid valve in response to a control signal from a combustion control means, the combustion control means outputs pulses at regular intervals to a relay drive circuit, and also outputs pulses at regular intervals to a relay drive circuit. Among them, the relay drive circuit of the solenoid valve corresponding to the burner that cannot directly transfer the flame from the burner where the spark plug and flame detection plug are facing detects the above pulse and outputs a combustion stop signal when the pulse disappears. An automatic stop device for a combustion device, characterized in that a pulse detection section is connected.
