摘要： A gas turbine engine (20) is provided that includes compressor (30) and combustor sections (32), inner and outer casings (52, 54), an annular diffuser (56), an inner diffuser casing (72), a heat exchanger (150), and a high-pressure stator vane stage (60). An annular combustor (35) is disposed radially inward of the outer casing (52) and has inner and outer radial wall structures (35A, 35B). The outer casing (52) and the combustor outer radial wall structure (35B) define a diffuser outer diameter flow path (164). The annular diffuser (56) directs diffuser gas towards the combustor section (32). The inner diffuser casing (72) is disposed radially inward of the annular combustor (35) and spaced apart from the combustor inner radial wall structure (35A). The inner casing (54) is disposed radially inward of and spaced apart from the inner diffuser casing (72). The inner diffuser casing (72) and the inner casing (54) define an intercooler fluid passage (104). The heat exchanger (150) is configured to produce intercooler gas. Intercooler gas is directed through the intercooler fluid passage (104) and into the high-pressure stator vanes (112).

摘要： An industrial gas turbine engine with first and stage turbine rotor blade cooling circuit in which the blade cooling air flows through a central passage within the rotor of the engine, flows through a space between first and second stage rotors, separates into two flows with one flow going to the first stage blades and the second flow going to the second stage blades, the two flows then collecting in a common manifold, where the spent blade cooling air flows forward through the first stage rotor and along a rotor cooling passage and into a stator cavity, where the cooling air then is discharged into a combustor.

摘要： A cooling system (10) configured to cool aspects of the turbine engine (12) between a compressor (14) and a turbine assembly (16) is disclosed. In at least one embodiment, the cooling system (10) may include one or more mid-frame cooling channels (18) extending from an inlet (20) through one or more mid-frame torque discs (22) positioned downstream of the compressor (14) and upstream of the turbine assembly (16). The inlet (20) may be positioned to receive compressor bleed air. The mid-frame cooling channel (18) may be positioned in a radially outer portion of the mid-frame torque disc (22) to provide cooling to outer aspects of the mid-frame torque disc (22) such that conventional, low cost materials may be used to form the mid-frame torque disc (22) rather than high cost materials with capacity to withstand higher temperatures. The cooling fluid routed through the mid-frame cooling channel (18) in the mid-frame torque disc (22) may be exhausted into a cooling system (10) for the downstream turbine assembly (16).
