A liquid fuel gasifying burner including an inner gasifying member connected to a rotary gasifying member of the frustoconical shape so that the two members can rotate as a unit. The inner gasifying member is formed with an air port in the central portion of its upper end and open at its lower end, and the rotary gasifying member is closed at its upper end and open at its base and rotatably mounted in a combustion cylinder open at its upper end and formed with an air blowing chamber in the central portion of its bottom. A fuel-air mixture passage is defined between the outer circumferential surface of the inner gasifying member and the inner circumferential surface of the rotary gasifying member, and a liquid fuel spreading surface having a liquid fuel scattering portion at its outer periphery is formed on the upper end of the inner gasifying member. A liquid fuel feed line opens at its forward end close to the liquid fuel spreading surface. The burner has a larger liquid fuel spreading surface, a larger atomized liquid fuel gasifying surface and a longer fuel-air passage than the prior art, to achieve complete combustion by producing a homogeneous mixture of gasified fuel and air. The liquid fuel spreading surface may be stepped.
