PURPOSE:To suppress accumulation of tar and to enchance combustion property, by providing a heating body in the neighborhood of the vaporizing surface of a vaporizing chamber, against which injected fuel from a fuel nozzle directly collides, and by making the vaporizing surface a film boiling zone for fuel, in a combustion apparatus of vaporized and pre-mixed combustion type, using kerosene for fuel, applied to a heating apparatus for domestic use. CONSTITUTION:A heater as a heating body, or a hot body 9 such as a fin which can easily receive heat rom combustion gas, is provided in the neighborhood of a vaporizing surface 1, that is the outer surface of a collided surface 7a, against which fuel injected into a vaporizing chamber directly collides. With such an arrangement, fuel injected from a fuel nozzle 6 directly collides against the collided surface 7a. The collided surface 7a is in a film boiling zone, so that most of the fuel is not vaporized on the collided surface 7a, but scatters and turns into small particles. Accordingly, fuel can be scattered to the larger area on a vaporizing surface 7, that is a film boiling aone or a core boiling zone. As a result, tar is hardly formed and accumulated on the collided surface 7a. |
