Abstract
Gas turbine engines have in the past attempted to control emissions by a variety of processes or in a variety of manners. For example, past systems have used water or steam injection, and gas turbine combustion systems have utilized a variety of approaches including premix systems and various fuel injector designs. The present system controls emissions by modulating air flowing through a fuel injector. The system utilizes a fuel injector having a passage defined therein in which a valve is positioned. The valve is movable between a maximum flow position and a minimum flow position. The valve is moved lineal by a lineal movement portion being activated by a cam portion, a ring gear and an actuating mechanism. Parameters of the gas turbine engine are monitored by a plurality of sensors, and interpreted by a computer which actuates the actuating mechanism and results in the fluid flow to a combustor section being controlled to meet preestablished emission parameters.
