摘要： A cooled cooling air (CCA) system (154) is provided for application with gas turbine cycles (10). In an embodiment of the invention, the CCA system includes a shell (158) and tube heat exchanger (160) in which water flow is provided inside the tube(s) and air flow is provided on the shell side. Water (202) exiting the heat exchanger is partially evaporated. Accordingly, the resulting two phase water/(steam flow is admitted to a separator (204) where the steam (164) and water (162) are separated. The saturated steam (164) is flowed to the HRSG (32) whereas the separator water (162) is recycled to the heat exchanger.

摘要： To provide auxiliary steam, a low pressure valve (62) is opened in a combined cycle system to divert low pressure steam (40) from the heat recovery steam generator (20) to a header (42) for supplying steam to a second combined cycle's steam turbine seals, sparging devices and cooling steam for the steam turbine if the steam turbine and gas turbine lie on a common shaft with the generator. Cooling steam (32) is supplied the gas turbine in the combined cycle system from the high pressure steam turbine (22). Spent gas turbine cooling steam may augment the low pressure steam supplied to the header by opening a high pressure valve (78) whereby high and low pressure steam flows are combined. An attemperator (74) is used to reduce the temperature of the combined steam (66) in response to auxiliary steam flows above a predetermined flow and a steam header temperature above a predetermined temperature. The auxiliary steam may be used to start additional combined cycle units or to provide a host unit with steam turbine cooling and sealing steam during full-speed no-load operation after a load rejection.

摘要： A heat recovery steam generation system (10) is provided. The heat recovery steam generation system includes at least one superheater (60, 62) or reheater in a steam path for receiving a steam flow and configured to produce a superheated steam flow. The system also includes an inter-stage attemperator (64) for injecting an attemperation fluid into the steam path. The system further includes a control valve (68) coupled to the inter-stage attemperator (64). The control valve (68) is configured to control flow of attemperation fluid to the inter stage attemperator (64). The system also includes a controller (66) coupled to the control valve (68) and the inter-stage attemperator (64). The controller (66) further includes a feedforward controller (92) and a trimming feedback controller (96). The feedforward controller (92) is configured to determine a desired amount of flow of the attemperation fluid and the trimming feedback controller (96) is configured to compensate for inaccuracies in the determined amount of flow of the attemperation fluid to determine a net desired amount of flow of attemperation fluid through the control valve (68) into an inlet of the inter-stage attemperator (64) based upon an outlet temperature of steam from the superheater (62). The controller (66) also determines a control valve demand based upon the flow to valve characteristics. The controller (66) further manipulates the control valve (68) of the inter-stage attemperator (64), and injects the desired amount of attemeration flow via the inter-stage attemperator (64) to perform attemperation upstream of an inlet into the superheater (62).

摘要： An inlet bleed heater for flowing heated air to the inlet of a compressor is fabricated wholly at a factory site. The heater interconnects a manifold (34) which receives extraction air from the compressor to down tubes (20) in the inlet air duct to supply heated extraction air to the ambient inlet air via piping (50) with bellows (53). The bellows accommodate thermal expansion and contraction of the manifold and the down tubes. The pipe and bellows lie within the height envelope of the bleed heater, facilitating transportation of the heater on its side within overall height and width limitations permitted for road travel.
