Abstract

PURPOSE: To obtairn a pre-mixed conbustion burner of compact size and facilitate air scanty diffusion flame and an air excessive pre-mixed flame by a method wherein the flame center line of a pre-mixed flame deviates from the center line of a diffused flame further as the former approaches the tip of its flame.
CONSTITUTION: A spray fuel 29 injected from a fuel atomizer 22 to the right and left direction is diffused and is mixed with the air for the combustion use injected from a diffusion flame type nozzle 21 and forms a diffusion flame C along a flame center line axis (C). An atomized fuel 27 being injected from the fuel atomizer 22 to the upward and downward direction penetrates a thin layer of the recirculated exhaust gas GR injected from a recirculated exhaust gas injection nozzle 28, bumps against the air for the combustion use injected from a pre-mixed flame type nozzle 40 and is diffused and mixed to form a pre-mixed gas, and then, it burns to form a pre-mixed flame W having a large air ratio. The air for the combustion use injected from the pre-mixed flame nozzle 40 is injected, at angle γ inclined off the flame center axis (C) of the diffusion flame C, as a result, a flame center line (W) is formed by angle γ inclined off the flame center axis (C) of the diffusion flame C.
