PURPOSE:To effectively reduce NOX contained in a combustion exhaust gas in simple and low cost structure. CONSTITUTION:A flame stabilization wall surface 2 is extended to the upper part of a rich mixture ejection port 1 which ejects a gas rich mixture upwards. A slit-shaped outlet 3 is formed on the flame stabilization wall surface 2 and divided up and down with a partitioning board 4. A secondary air outlet 5 is installed to an area on the upper side of the slit-shaped outlet 3. A light mixture ejection port 6, which ejects air rich-light mixture is installed to an area on the lower part of the slit-shaped outlet 3, that is, an area near the light mixture ejection port 6. Furthermore, it is also acceptable to install a secondary air outlet, which is different from the secondary air outlet 5 to the slit-shaped outlet 3 in the area nearer the rich mixture ejection outlet 1 than the lean mixture ejection port 6. |
