常検出装置。In a combustion device that preheats a combustion section and starts combustion by supplying liquid fuel after completion of preheating of the combustion section, a preheating raw signal is output during preheating of the combustion section, and when preheating of the combustion section is completed. a signal generation circuit that outputs a preheating completion signal in response to the preheating completion signal; a timer circuit that starts a timer operation in response to the preheating completion signal from the signal generation circuit, times up after a certain period of time has elapsed, and outputs a timeup signal; The flame detection circuit detects the presence or absence of combustion flame in the combustion section, and if it is determined that a non-flame detection signal is output from the flame detection circuit when the time-up signal is output from the tough circuit, an abnormality detection signal is generated. and means for outputting an abnormality detection signal when a flame detection signal is output from the flame detection circuit while the preheating signal is being output from the signal generation circuit.
