PURPOSE:To reduce electric power consumption, by a method wherein a hollow cylindrical heat receiving tube is provided at the center of a flame port tube, on which a multitude of small holes is bored, and an electric heater is provided on the lower surface of the evaporating surface of the heat receiving tube while an air chamber and an air passageway are provided on the outer peripheral side and at the lower part of the flame port tube to supply air from the inner peripheral side of a combustion chamber. CONSTITUTION:When an electric heater 3 is conducted, an evaporating surface 1a is heated. When the temperature of the evaporating surface 1a has arrived at an evaporating temperature or higher, a fuel pump 9 is operated to discharge fuel onto the evaporating surface 1a at the bottom of a combustion chamber 6 through a fuel nozzle 8. At the same time, a fan 10 is operated and air is supplied into the combustion chamber 6 from an air outlet port 2a through small holes 4a, bored on a flame port tube 4, and air passageway 2 in the heat receiving tube. The fuel, discharged on the evaporating surface 1a, is contacted with the surface of a high temperature and is evaporated, then, is ascended while being mixed with the air, supplied through the small holes 4a at the lower part of the flame port tube 4. The ascended mixture gas is burnt while being mixed with and diffused into the air, supplied through the air outlet port 2a provided at the upper part of the heat receiving tube 1 and the small holes 4a at the upper part of the flame port tube 4. Accordingly, the fuel is burnt while evaporating itself by the combustion heat of itself upon combustion, and therefore, the conduction of current through the electric heater becomes unnecessary and electric power consumption may be reduced.
