おける燃焼炎検知装置。 In a combustion device that supplies fuel to a burner and uses an igniter to ignite the fuel in the burner to start a combustion operation, a flame rod is provided near the burner, and when a combustion flame is generated, the flame is transmitted through the flame rod and the combustion flame. A flame current energizing circuit that passes current and a flame current value of this flame current energizing circuit are detected, and when this current value reaches a relatively low first level within a relatively short preset time, it is determined that the combustion state is normal. If the flame current value reaches a relatively high second level within a relatively long time set in advance, it is determined to be a normal combustion state. A combustion flame detection device for a combustion apparatus, characterized in that a determination means is provided for determining an abnormal combustion state if the second level is not reached.
