Fuel spraying method in liquid fuel combustion burner, and liquid fuel combustion burner

Method for spraying a liquid fuel together with a spray-inducing fluid mixed in the fuel, and a burner, in which the liquid fuel is mixed with the spray-inducing fluid while rotating the liquid fuel in flow passages of injection holes (4), 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 NOx and generation of soot.
