专利汇可以提供Fuel burner nozzle专利检索，专利查询，专利分析的服务。并且In a pressure atomized oil burner having air louvers to swirl primary air, a long narrow flame is produced without reducing heat release by using a nozzle tip having cylindrical ducts drilled at a compound angle in the direction of the air swirl in addition to the main cone angle.，下面是Fuel burner nozzle专利的具体信息内容。
1. A nozzle for swirling pressure atomized fuel to produce a long narrow flame, comprising: a nozzle body; an internal passageway in said nozzle body open at one end and closed by a hemispherical chamber at the other end, said passageway being symmetrical about the longitudinal centerline of said nozzle body; the nozzle body having an external surface at the closed end in the form of a truncated cone forming a nozzle body cone angle having its apex forward of said closed end and symmetrical about the longitudinal centerline of said nozzle body; and a plurality of cylindrical ducts in said nozzle body piercing the external conical surface and communicating with said hemispherical chamber, each of which is positioned with a main cone angle and lead angle.
2. The nozzle of claim 1 wherein said nozzle body cone angle is an acute angle of 45 to 50 degrees.
3. The nozzle of claim 1 wherein said main cone angle is an acute angle of 28* to 32* .
4. The nozzle of claim 1 wherein said lead angle is an acute angle of 8* to 12* .
5. The nozzle of claim 1 wherein said plurality of cylindrical ducts are equally spaced.
6. The nozzle of claim 1 wherein said lead angle is positioned in the direction of external air swirl.
