Abstract
A gas turbine combustion system includes a plurality of combustors within a pressure vessel, each combustor including a combustion liner defining a combustion chamber having a reaction zone and a dilution zone, the liner in the dilution zone provided with a plurality of circumferentially spaced dilution air feed holes. A flow shield surrounds each combustion liner in radially spaced relation thereto for feeding compressor discharge air to the combustion chamber. Air staging apparatus directly controls the amount of compressor discharge air fed into each combustion chamber dilution zone via the dilution air feed holes. The apparatus includes a plurality of pressure vessel extraction ports and associated conduits for introducing compressor discharge air into a first manifold common to the plurality of combustors; a dilution air control valve located between each extraction port and the first manifold; and a second, annular manifold surrounding the flow shield and including feed tubes connecting the second manifold to each of the dilution air feed holes in the combustion liner.
