PCT No. PCT/JP82/00102 Sec. 371 Date Nov. 22, 1982 Sec. 102(e) Date Nov. 22, 1982 PCT Filed Apr. 5, 1982 PCT Pub. No. WO82/03444 PCT Pub. Date Oct. 14, 1982.A liquid fuel combustion device which includes a fuel tank, a combustion section which includes an inner and an outer flame cylinder and an outer cylinder surrounding the flame cylinders, and a wick having one end in the fuel tank for being immersed in the liquid fuel therein and the other end disposed between the flame cylinders so as to draw fuel to the other end. Structure is also provided for guiding air through the combustion section to provide oxygen to support combustion between the flame cylinders of fuel evaporated from the wick such that the heat produced by the combustion serves to evaporate the fuel from the other end of the wick. Detector elements are provided for respectively detecting the temperature of the exhaust gas from the combustion section and the temperature of the air guided to the combustion section by the guide structure. Circuitry is provided for producing a signal indicative of the difference between the respective temperatures detected by the respective temperature detecting elements. An actuating section is provided to stop the combustion in the combustion section or give a warning when the difference the outputs of the detecting elements is below or above a predetermined value. In one embodiment of the invention, an electric heater is provided for assisting evaporation of fuel from the wick when the temperature difference detected by the temperature detecting elements is less than a predetermined value. |
