  • Energy recovery and steam supply for power augmentation in a combined cycle power generation system
    Patent number: 8539750
    Abstract: A power generation system (11) and method of operating such a system (11) including a steam turbine (14). In one embodiment a HRSG (20) includes an evaporator (127) coupled to receive condensate from the steam turbine (14), and a superheater (132) coupled to receive output from the evaporator (127). The HRSG (20) generates steam with thermal energy received from a combustion turbine (28). A flash tank (9) receives water heated in the HRSG (20), outputs a first portion of the water as steam, and outputs a second portion of the water as liquid. A flow line (134) passes steam (51) from the flash tank (9) to a combustion chamber (26) in the combustion turbine (28) to provide power augmentation.
    Type: Grant
