Abstract

A fuel gasifying burner including a combustion cylinder, a rotary shaft extending into the combustion cylinder through its open base, a frustoconical rotary gasifying member connected to the rotary shaft and formed at a lower end of its wall with a bent portion extending outwardly and having at its peripheral end a liquid fuel scattering end, and an inner gasifying member located inside the rotary gasifying member to form a unit therewith and having connected to a lower end of its wall a fuel air-mixture gas diffusing wall extending outwardly a greater distance than the bent portion of the rotary gasifying member. The inner gasifying member is formed at its forward end with an air supply opening communicated through an air passage with an air blowing chamber. An annular flame ejecting upright wall is formed contiguous with a fuel-air mixture gas diffusing wall and provided at its end with a liquid fuel rescattering portion. When a fuel-air mixture gas is ejected through a gas ejecting passageway between the two gasifying members, the pressure under which the gas is ejected is reduced as the gas impinges on the flame ejecting upright wall, so that the gas can be diffused into the interior of the combustion cylinder in flames of reduced vigor.
