Compressor clearance control system and method for providing clearance control

摘要

The present application provides a compressor clearance control system (100) for a gas turbine engine (10). The gas turbine engine (10) includes a turbine (40) producing exhaust gases and a compressor (20) with a casing (24) and a number of rotor blades (26). The compressor clearance control system (100) may include an casing heat exchanger (110) positioned about the casing (24) of the compressor (20) and an extraction (120) of exhaust gases from the turbine (40). The extraction (120) is in communication with the casing heat exchanger (110) so as to heat the casing (24) of the compressor (20) with the exhaust gases from the turbine (24).
