Kerosene boiler



PROBLEM TO BE SOLVED: To permit the improvement of response property of a temperature detecting means with respect to abnormal combustion by preventing an exhausting unit from becoming an abnormal high temperature in accordance with the abnormal combustion of a kerosene burner. SOLUTION: A kerosene boiler is provided with a fan 5, a kerosene burner 3, to which combustion air is supplied by the fan 5, a fuel supplying means 4, supplying kerosene fuel to the kerosene burner 3, a heat exchanger 6, heated by the combustion of the kerosene burner 3, a muffler 7, connected to the heat exchanger 6, and an exhausting unit 18, discharging combustion waste gas, passing through the muffler 7. Further, the kerosene boiler is provided with a temperature detecting means 30, detecting the internal temperature of the muffler 7, and an abnormal time fire extinguishing means 43, stopping the combustion of the kerosene burner 3 when the internal temperature of the muffler 7, which is detected by the temperature detecting means 30, has risen to a value higher than a predetermined temperature.
