In a liquid fuel burner wherein a fuel gasifying member is directly supported by a rotary shaft inserted in a main body of the burner for converting liquid fuel into gasified form, a water evaporation chamber of the annular shape is arranged at the corner of a top portion of the fuel gasifying member and filled therein with a water evaporation promoting material. Water is supplied to the water evaporation chamber and quickly converted into water vapor which is ejected into the fuel gasifying member through steam ejection apertures formed in the water evaporation chamber as the fuel gasifying member is rotated and performs the liquid fuel gasifying function, and the gasified fuel and water vapor form a mixture with air supplied under pressure, the mixture being ejected into the main body of the burner to sustain combustion of liquid fuel in gasified form, so that the consumption of thermal energy can be reduced by using water as part of the liquid fuel. Steam ejection apertures may also be formed in an outer wall of the water evaporation chamber to cause excess water vapor to be ejected therethrough into the main body of the burner where it burns with the flames of combustion of gasified fuel. The fuel gasifying member may include formed integrally therewith a skirt disposed at its bottom portion which is formed therein with gas ejection slits and which includes a lower portion received in a gas accumulation chamber formed in the main body of the burner to define a gasified fuel-air mixture passageway between the skirt and the gas accumulation chamber, the main body having a cold air passageway formed in its outer peripheral portion. Thus, a mixture of gasified fuel, water vapor and air can be ejected through the gasified fuel-air mixture passageway and the ejection slits to sustain combustion in a large area.
