摘要:
This combined cycle gas turbine plant has a gas turbine (104) and a steam turbine (106) mounted on the same shaft. A control system is configured for switching the plant from a rated mode of operation, in which the plant is operated on gas turbine output and steam turbine output, to a reduced load mode of operation, in which the plant is operated on gas turbine output alone. The switch from the rated mode of operation to the reduced load mode of operation occurs if plant demand decreases below a predetermined threshold. The steam turbine is run under full speed no load conditions in the reduced load mode of operation, and is heated using controlled steam admission, to maintain the steam turbine in a heated ‘stand-by’ state.

A turbomachine passage cleaning system (27) includes a first airflow passage (30) having a first inlet (32) configured and disposed to fluidly connect to a compressor portion (4), a first outlet (33) configured and disposed to fluidly connect to a turbine portion (6), and a first intermediate portion (34) including a first strainer (36). A second airflow passage (40) is fluidly coupled to the first airflow passage (30). The second airflow passage (40) has a second intermediate portion (44) having second strainer (46). A first valve (38) is arranged in the first intermediate portion (34) upstream from the first strainer (36), and a second valve (48) is arranged in the second intermediate portion (44) upstream from the second strainer (46). The first and second valves (38,48) are selectively operated to control fluid flow into respective ones of the first and second airflow passages (30,40) to filter air passing from a turbomachine compressor portion (4) to a turbomachine turbine portion (6). Corresponding turbomachine and method of filtering an airflow are also provided.

A system includes a mixing assembly (50) configured to mix a liquid fuel (42) and a water (15) to generate a fuel mixture (80). The fuel mixture (80) is configured to combust in a combustor (16) of a gas turbine (11). The mixing assembly (50) includes a liquid fuel passage (70) disposed in an integrated housing. The liquid fuel passage (70) is configured to flow the liquid fuel (42) and to exclude liquid traps. The mixing assembly (50) also includes a water passage (74) disposed in the integrated housing. The water passage (74) is configured to flow the water (15) and to exclude liquid traps. The mixing assembly (50) also includes a mixer (78) disposed in the integrated housing (150) and coupled to the liquid fuel passage (70) and the water passage (74). The mixer (78) is configured to mix the liquid fuel (42) and the water (15) to form the fuel mixture (80).
摘要:
An oxygen fired power generation system is disclosed. The power generation system has a high pressure combustor having a water recycle temperature control subassembly, and an intermediate pressure combustor having a C02 recycle temperature control subassembly. Thus, a first energy cycle utilizes a first energy source operatively associated with a corresponding first heat sink, and a first inert agent to provide energy transfer therebetween and temperature control during operation of the first energy source. In like fashion, a second energy cycle utilizes a second energy source operatively associated with a corresponding second heat sink, and a second inert agent to provide energy transfer therebetween and temperature control during operation of the second energy source. The first and second energy sources are not identical, the first and second heat sinks are not identical and the first and second inert agents are not identical. The first and second energy cycles are configured in combination to provide a power generation unit.
