PROBLEM TO BE SOLVED: To provide a fuel combustor capable of stopping combustion before the concentration of CO2 reaches 1% regardless of maximum combustion or minimum combustion without using a CO2 sensor, etc. SOLUTION: The fuel combustor is provided with a room temperature sensor capable of automatic operation including the maximum combustion and the minimum combustion. The fuel combustor is provided with a means for obtaining a room temperature at a predetermined concentration of CO2, on the basis of the correlation at a predetermined condition in the sealed room between the room temperature on combustion and the concentration of CO2; and for memorizing the room temperature for a flame failure setting temperature. At the operation of the minimum combustion, the maximum combustion is temporarily operated (S6) during the shorter time period of either the room temperature detected by the room temperature sensor reaching the fire failure setting temperature or an elapsed predetermined time. After the elapse of the shorter time period, the combustion is switched to the minimum combustion (S8). |
