Abstract
Systems for controlling the combustion air to be used with a gas turbine engine for control the products of combustion and reducing emissions emitted therefrom have been used in the past. The present system includes a compressed air plenum being divided into a combustion air supply portion and a dilution or cooling air supply portion. A variable geometry system is positioned between the compressor section and the compressed air plenum. The variable geometry system is movably between an open position and a closed position. Movement of the variable geometry system varies the distribution of the compressed air between the combustion air supply portion and the dilution or cooling air supply portion. The system reduces emissions emitted from the gas turbine engine.
