  • Power plant heat recovery system having heat removal and refrigerator systems
    Patent number: 8074458
    Abstract: A heat recovery system for a turbomachine system includes a heat removal system and a refrigeration system. The heat removal system is fluidly connected to at least one component of the turbomachine system. The heat removal system passes a cooling fluid through the at least one component to absorb heat. The refrigeration system is operatively connected to the heat removal system. The refrigeration system extracts the heat from the cooling fluid passing through the at least one component of the turbomachine system to produce a cooling effect.
    Type: Grant
    Filed: July 31, 2008
    Date of Patent: December 13, 2011
    Assignee: General Electric Company
    Inventors: Prakash Narayan Govindan, Anil Kumar Sharma, Shinoj Vakkayil Chandrabose
  • Heat recovery system for a turbomachine and method of operating a heat recovery steam system for a turbomachine
    Patent number: 8037703
    Abstract: A heat recovery system includes a source of waste heat, and a refrigeration system operatively connected to the source of waste heat. The refrigeration system is capable of extracting heat rejected from the source of waste heat to form a cooling medium.
    Type: Grant

  • Ejector-OBB Scheme for a Gas Turbine
    Publication number: 20110162386
    Abstract: A cooling circuit in a gas turbine includes an over board bleed (OBB) circuit bleeding air from a last stage of the compressor, an extracted air circuit extracting air from an upstream stage of the compressor, and an ejector receiving input from the OBB circuit and the extracted air circuit. Ejector outlet flow from the ejector is communicated to the turbine.

  • System and method for use in a combined or rankine cycle power plant
    Patent number: 7748210
    Abstract: A system is provided and includes a first condenser configured to fluidly receive a first steam supply and tower water and to output a first water supply, a second condenser configured to fluidly receive a first portion of a second steam supply and the first water supply and to output a second water supply, and a vapor-absorption-machine (VAM) configured to fluidly receive a second portion of the second steam supply and the second water supply by which a refrigeration cycle is conducted to thereby cool at least one of the tower water and a third water supply used to cool the tower water.
