PROBLEM TO BE SOLVED: To prevent erroneous detection during transient period of combustion when adhesion of tar is detected based on the temperature at a vaporizing section and the output from a frame rod. SOLUTION: A combustor comprises a vaporizing section 32 arranged with a chamber 37 for vaporizing fuel, a heater 42 for heating the vaporizing section 32, a nozzle 34 for ejecting vaporized gas, a burner section 44 for combusting vaporized gas, a first temperature detector 49 disposed closely to the inlet of the vaporization chamber 37, a second temperature detector 50 disposed at the vaporizing section 32 in the vicinity of the nozzle 34, a flame rod 47 for detecting flame current, a section 53 for operating the temperature difference between the inlet and outlet of the vaporization chamber 37, means 48 for determining combustion state from the flame current, and a combustion operation control section 56 wherein combustion operation is controlled based on the outputs from the temperature operating section 53 and the combustion determining means 48 only when the combustion state is stable.
