<p>PURPOSE:To reduce the generation of NOx by a method wherein combustion, such as subdivision combustion, thick-and-thin fuel combustion, self-recirculation combustion, is delicately executed in a burner. CONSTITUTION:A plurality of radially injecting nozzles 2 through which gas is injected are formed radially of the vicinity of the tip part of a gas pipe and a flame stabilizing plate 3 is arranged to the tip part of the gas pipe. A partition plate 4 having approximately the same size as that of the flame stabilizing plate 3 is arranged to the outer periphery of the gas pipe slightly on the upper stream side of the radial injection nozzle. An air pipe 5 is provided outside the gas pipe and a number of air revolving vanes 6 are arranged to the outer periphery of the partitioning plate 4 in the air pipe. A gas nozzle 8 of a gas tube connected to the gas pipe is installed between the air revolving vanes. This constitution delicately executes combustion, such as subdivision, thick-and-thin fuel combustion, and self-recirculation combustion.</p> |
