LIQUID FUEL BURNER

PURPOSE:To evaporate and vaporize the liquid fuel at a relatively low temperature and supply the gaseous fuel to combustion by providing a liquid fuel dripping means which atomizes the liquid fuel and drips it in the upper section of an evaporation chamber and directly evaporating the dripping fuel by the ascending air flow developed by the heated air. CONSTITUTION:At the upper ceiling section of an evaporation chamber 11, a fuel tank 21 and a plurality of hollow needles 22 as a liquid fuel dripping means are provided. The hollow needles 22 project from the bottom of the fuel tank 21 towards the evaporation chamber 11, and they also project into the fuel tank 21 by the height of H. The liquid fuel in the fuel tank 21 is dripped in small particles through the small holes in the hollow needles 22 to the evaporation channel 11. The air that is heated by a heater 15 is led to the evaporation chamber 11 through an introduction pipe 12, and flows upwards as an ascending air flow. The liquid fuel that is dripped as small particles from the hollow needles 22 makes contact with the ascending air, and is evaporated and vaporized. And, the fuel becomes a mixture gas and is sent to the combustion section 143 through a discharge pipe 13 and there it burns.
