  • Fuel spraying method in liquid fuel combustion burner, and liquid fuel combustion burner
    Patent number: 5176324
    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.
