PURPOSE: To prevent supply particles from being entrained within an oxidant and a fuel flow by providing upper and lower oxidant nozzles such that the nozzles are located upper and lower of a fuel jet and upper and lower oxidant jet with a fan shape branched outward are produced. CONSTITUTION: A burner 10 includes a fuel nozzle 12, which nozzle forms a fan shaped fuel jet branched outward. Such a combustion jet combusts as a frame branched extending outward in a proper shape oxidant jet. Upper and lower oxidant nozzles 14 and 16 are provided to produce outward branched fan shaped upper and lower oxidant jets located upper and lower portions of the fan shape branched outward and located upper and lower of the fuel jets. The oxidant has higher pressure than a fuel and hence the oxidant is sucked into the fuel. |
