TRIPLE SWIRL GAS TURBINE COMBUSTOR

摘要

PURPOSE: A triple swirl-type gas turbine combustion device is provided to improve fuel flexibility by burning both LCV(Low Calorific Value) and HCV gas. CONSTITUTION: A triple swirl-type gas turbine combustion device comprises a case(100), a compressed air inlet(110), a combustion liner(130) and a burner. An igniter(120) is attached to the case. The compressed air inset receiving the compressed air from a gas-turbine compressor is formed at one side of the case. The combustion liner causes ignition with the igniter. The combustion liner comprises a plurality of cold air inlet holes(135). The burner comprises a plurality of air supplying swirlers(200). The swirlers are installed at the inner side of the burner head(140) of the upper part of the combustion liner and enable the compressed air to be swirled. The swirlers comprise a swirl vane, respectively.
