た複合燃焼装置。1. Exhaust gas from two sets of combustion devices having a heat exchange section, a burner, and an air supply fan for supplying combustion air to a combustion chamber accommodating the burner, is exhausted in common via an exhaust collecting cylinder. In the combined-combustion device of the type that discharges from the road, the abnormality detection means for detecting abnormality of each part other than the air supply fan of the first combustion device (1) on the one hand and the second combustion device (2) on the other hand is individually provided. The output signal is input to the control circuit (3a), and the control circuit (3a) is equipped with the abnormality detection means when a signal corresponding to the abnormal state is output from any one of the abnormality detection means. The operation of each part other than the air supply fan of the combustion device on the operated side is stopped, and fan abnormality detection means (3) for detecting an abnormality of the air supply fan (11) of the first combustion device (1)
Only when the outputs from 1) and the fan abnormality detection means (32) for detecting the abnormality of the air supply fan (21) of the second combustion device (2) both output the signal corresponding to the normal state. A combined combustion system equipped with a determination device (3b) that keeps both air supply fans in continuous operation.
