摘要： PROBLEM TO BE SOLVED: To make NOx in exhaust gas extremely low by diverging part of discharge air of a compressor at the inner diameter face of a compressor outlet, compressing this air in a compression stage positioned on the lower side of an internal wall of a main compressor outlet diffuser, and installing the main compressor outlet diffuser downstream adjacently to an auxiliary compressor. SOLUTION: A combustion turbine 10 has a plural rows of compressor blades, and a set 20 of a fixed blade and an outlet guide blade is provided directly downstream of the compressor blade 12 in the last row. Air flow passing through this set 20 flows through a main compressor outlet diffuser 30. Main air flow in this diffuser 30 is divided in a main part 32 and auxiliary air flow 34 by an internal wall (partition) 36, and the auxiliary air flow 34 is led to an auxiliary air compressor 50 arranged adjacently to the lower side of the internal wall 36 of the main compressor outlet diffuser 30. The auxiliary air compressor 50 is driven by a center main shaft 11 of the combustion turbine 10 so as to compress the auxiliary air flow 34 and to lead it again into a member to be cooled. Performance of the turbine is thereby improved, and extra-low NOx is emitted.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of an intercooler-integrated axial flow compressor with simplicity in its structure added and no increase in its manufacturing costs by providing a cooling means in a gas passage through which gas circulates in the operation of the compressor, which receives cooling water therein and absorbs heat from circulating gas to cool the gas in the operation of the compressor. SOLUTION: In its normal operation an axial flow compressor 320, typically of an intercooler-integrated type, inducts atmospheric air or gas and produces compressed gas 322. In its compression process gas 322 is cooled inside the axial flow compressor 320 by cooling water 372 led thereinto from a cooling tower 370. The cooling water 372 is made to pass through one or more stator blade assemblies, or an air-towater heat exchanger or a recuperative heat exchanger 360 disposed in the gas passage for the axial flow compressor 320. The heat exchanger 360 also inducts cooling water and absorbs heat from gas passing therethrough in the operation of the compressor 320. The compressed gas is thus continuously intercooled with a simple structure.
