  • Compressor clearance control system using turbine exhaust
    Patent number: 8172521
    Abstract: The present application provides a compressor clearance control system for a gas turbine engine. The gas turbine engine includes a turbine producing exhaust gases and a compressor with a casing and a number of rotor blades. The compressor clearance control system may include a casing heat exchanger positioned about the casing of the compressor and an extraction port for exhaust gases from the turbine. The extraction port is in communication with the casing heat exchanger so as to heat the casing of the compressor with the exhaust gases from the turbine.
    Type: Grant
    Filed: January 15, 2009
    Date of Patent: May 8, 2012
    Assignee: General Electric Company
    Inventors: Steven W. Tillery, Mark W. Flanagan, David A. Snider
  • Compressor clearance control system using bearing oil waste heat
    Patent number: 8152457
    Abstract: The present application provides a compressor clearance control system for a gas turbine engine having an oil recirculation system with a flow of oil therein and a compressor with a casing and a number of rotor blades. The compressor clearance control system may include a casing heat exchanger positioned about the casing of the compressor and a conduit in communication with the casing heat exchanger and the oil recirculation system so as to heat the casing of the compressor with the flow of oil from the oil recirculation system.
