发明名称 Active control of compressor extraction flows used to cool a turbine exhaust frame
摘要 A gas turbine (10) includes at least one combustor (14) and an exhaust frame (18); a compressor (12) adapted to supply air to the combustor (14) and to supply bleed air to the exhaust frame (18). A cooling air supply duct (22) is arranged to supply ambient air to the exhaust frame (18) and at least one ejector (20) is arranged to supply the bleed air to the cooling air supply duct (22) upstream of the exhaust frame (18). A control valve (30) is configured to control the supply of compressor bleed air to the cooling air supply duct (22) and to the exhaust frame (18) as a function of turbine exhaust temperature and/or turbine load conditions and cooling requirements at the various turbine load conditions.
