Abstract

Abstract A burner wherein a fuel gasifying member is non-rotatably mounted in a main body of the burner and maintained in communication with a gas chamber formed in an outer marginal portion of the main body of the burner, 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. The liquid fuel thus scattered in the main body is ignited and burns to heat the fuel gasifying member in which the fuel supplied by the liquid fuel scattering means under the influence of an air blast supplied under pressure through an air supply duct is quickly gasified and forms a mixture of gasified fuel and air which is ejected through the gas chamber to sustain combustion of the liquid fuel in gasified form. A cooling chamber may be provided adjacent an inner wall plate of the main body of the burner. Heat dissipating fins may be attached to inner periphery of the non-rotatable fuel gasifying member. A cylindrical air guide may be arranged within the fuel gasifying member and maintained in communication with the air supply duct, with a narrow gasified fuel air mixture passageway being formed between the cylindrical air guide and the fuel gasifying member and connected to the gas chamber.
