The present invention relates to a burner for combustion apparatus employing a so-called multistage atomization system in which a tip of a nozzle is blocked, an outer peripheral surface has an inclined portion formed therein, fuel is forced in a string-like pattern through a multiplicity of outflow passageways formed on the inclined portion while at the same time the flow of air is substantially brought to intersect thereto at right angles for atomized disintegration and the fuel flowing along the inclined portion is formed into substances in the form of film and subject to filmed disintegration at the top of a frustoconical portion.

A burner for combustion apparatus comprising an atomizer and a nozzle within said atomizer to define an air passageway therebetween, said nozzle defining an axial fuel passageway disposed interiorly of said nozzle, a tip portion, a first frustoconical portion diverging in the downstream direction a first conical portion converging in the downstream direction extending from the widest portion of the first frustoconical portion, said first frustoconical portion and said first conical portion blocking said tip portion, said first frustoconical portion diverging from said tip portion toward the extreme end of said nozzle and defining a plurality of fuel outflow passageways connected to said axial fuel passageway, said fuel outflow passageways being positioned to flow fuel backwardly from the fuels forwardmost position in the axial fuel passageway until met by air passing over the diverging first frustonical portion, and a second frustoconical portion diverging in the downstream direction extending from the narrowest portion of said first conical portion converging in the downstream direction.
