System and method for controlling the combustion in a gas turbine with annular combustor

摘要

A gas turbine system is composed of a gas turbine engine (1), and a controller (2). The gas turbine engine (1) includes an annular combustor (3), and a turbine (4) driven by combustion gas from the annular combustor (3) to rotate on a longitudinal centerline axis of the gas turbine engine (1). The annular combustor (3) is comprised of an outer casing (6), a liner (7) disposed in the outer casing (6), and a plurality of dilution air regulators (12) introducing dilution air into the liner (7). The plurality of dilution air regulators (12) are circumscribed about the longitudinal centerline axis and spaced apart at substantially equal intervals. The controller (2) controls the plurality of dilution air regulators (12) to individually adjust dilution air flows through the plurality of dilution air regulators (12) into the liner (7). <IMAGE>
