<p>A method and apparatus are provided for reducing NOx emissions in dual stage, dual mode gas turbine combustors. The gas turbine combustor includes first (25) and second (26) combustion chambers separated by a reduced diameter throat section (100). The throat section is formed by converging and diverging wall sections constructed of porous material. A liner (101) is provided in surrounding relationship to the throat region to form a plenum by which predetermined amounts of air are metered into the plenum and permitted to pass through the porous throat wall sections. <IMAGE></p> |
