Abstract

PURPOSE:To enable the kind and degrees of an abnormality to be judged by a method wherein an abnormal state of combustion is judged by monitoring a gas pressure and an air pressure corresponding to a rate of load. CONSTITUTION:A memory device 11 stores a gas pressure and an air pressure corresponding to a rate of load under a normal combustion. A calculator device 12 operates a rate of variation of a gas pressure sensed by a gas pressure sensor 7 or an air pressure sensed by an air pressure sensor 8 in respect to data under a normal combustion, the operated value is stored in the memory device 11 and applied as a reference value when an abnormal state of combustion is judged. When an abnormal state of a combustion device (a gas burner) is detected, a gas pressure and an air pressure corresponding to the rate of load are monitored so as to judge an abnormal state of combustion. That is, in the case that an abnormal combustion occurs, the gas pressure or air pressure may be varied in reference to each of their reference values. With such an arrangement as above, it is possible to judge the kind and degrees of an abnormality in reference to this amount of variation.
