PURPOSE:To suppress the generation of soots and the like in a transition period from ignition to steady combustion by providing an annular spraying pipe of the titled liquid fuel combustion apparatus such as a tap-controlled water boiler or the like, the spraying pipe thereof has a lot of minute nozzles, within a premixing region as a means for pulverizing a liquid fuel. CONSTITUTION:To a fuel tank is connected an annular spraying pipe 4 having a fuel pump and a number of minute nozzles 3 as pulverizing means through an oil feed pipe 1 on a concentric circle. The annular spraying pipe 4 and an ignition device 5 are incorporated in a contiguous manner at the bottom part 8 of a combustion chamber 7 formed by a part of a combustion cylinder 6. By this arrangement, diffusion and mixing of the fuel are rapidly carried out and vaporization and diffusion of the fuel in the air are easily promoted, thereby local diffusion and mixing of the fuel within the premixing region of the combustion chamber are made uniform, and generation of soots and the like in the transition period from the ignition to the steady combustion can be suppressed. |
