A burner wherein a fuel gasifying member is non-rotatably mounted and disposed in spaced juxtaposed relationship to a gas accumulation chamber formed in a main body of the burner receiving an air supply duct inserted through one side, and liquid fuel scattering means is rotatably mounted at an open end portion of the fuel gasifying member for scattering a liquid fuel in minuscule particles into the interior of the fuel gasifying member and the main body of the burner through a scattering gap. A skirt formed therein with gas ejection slits is mounted at the periphery of the liquid fuel scattering means and has a lower half portion received in the gas accumulation chamber to define a forwardly directed annular gas ejection passageway between the skirt and gas accumulation chamber. A cylindrical air guide may be mounted within the fuel gasifying member and maintained in communication with the air supply duct. A cooling air passageway communicating with the air supply duct may be provided in an outer marginal portion of the main body of the burner, while a scattering surface of the liquid fuel scattering means may be inclined outwardly so as to cause the gas ejection passageway to incline outwardly, by eliminating the skirt. The gas ejection slits in the skirt may be inclined in any direction and the skirt itself may be inclined inwardly, so that the gas ejection passageway may be inclined outwardly. By virtue of these arrangements, the flames of combustion of the fuel in gasified form can be kept from being concentrated on the fuel gasifying member, so that it is possible to avoid damage which would otherwise be caused to the fuel gasifying member by the flames of combustion. An air ejection chamber may be formed outside the gas accumulation chamber and maintained in communication with the cooling air passageway for ejecting air under pressure toward the inner surface of the main body of the burner. By this arrangement, an air stream can be supplied to a portion of the inner surface of the main body of the burner on which the liquid fuel scattered in minuscule particles impinges, so that the liquid fuel in minuscule particles can be kept in fluid condition and its ignition and combustion can be facilitated. |
