Abstract: A burner for burning liquid fuel is provided, which atomizes liquid fuel together with an atomizing medium mixed with the fuel. The inhibition of generation of NOx in exhaust gas and that of generation of soot and dust are caused to be compatible by the burner, and the manufacturing properties are improved and the turndown ratio is increased.

Abstract: Disclosed are a fuel spraying method in a liquid fuel combustion burner for spraying a liquid fuel together with an atomization-promoting fluid mixed in the fuel, and a liquid fuel combustion burner, in which the liquid fuel is mixed with the atomization-promoting fluid while turning the liquid fuel in flow passages of injection holes, and streams injected from the injection holes are caused to impinge against one another in the presence of combustion air in a combustion apparatus. According to this fuel spraying method and this liquid fuel combustion burner, the atomization of the liquid fuel is promoted and the flame is dispersed while promoting the contact with air, and it therefore becomes possible to simultaneously control generation of NO.sub.x and generation of soot.

Abstract: Disclosed is a liquid spraying method in a liquid combustion burner, in which a liquid fuel is sprayed together with an atomization-promoting fluid mixed into the liquid fuel, and also a liquid fuel combustion burner is disclosed. In this liquid fuel spraying method and this liquid fuel combustion burner, only the liquid fuel is turned while the atomization-promoting fluid is not turned, whereby the frictional energy between the atomization-promoting fluid and the liquid fuel is reduced and hence, formation of NO.sub.x is controlled.
