Method for operating a gas turbine plant and gas turbine plant for implementing the method

摘要

#CMT# #/CMT# The method involves burning combustion fuels (5, 10) in combustion chambers (4, 9) under application of compressed air (3) and formation of hot gases (6, 11). The hot gases are released from turbines (7, 12) under cork performance, and the compressed air is removed from a compressor (1) and guided as cooling air flows (20, 22-24) for cooling thermally loaded component in the combustion chamber and/or turbine. The cooling air flows reaching a specified operational target are regulated by regulating elements (15-17, 21) depending on the operational target. #CMT# : #/CMT# An independent claim is also included for a gas turbine system. #CMT#USE : #/CMT# Method for operating a gas turbine system. #CMT#ADVANTAGE : #/CMT# The cooling air flows reaching the operational target are regulated by the regulating elements depending on the operational target, thus allowing effective control of the gas turbine system to select different operating targets with high overall efficiency without losses and wastage, and reducing the hot gas temperature in a simple manner for prolonging the service life of the combustion chamber in the gas turbine system. The gas turbine system is designed such that the flexible adaptation of cool air system with the operational target is realized for effective operation of the gas turbine system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a gas turbine system. 1 : Compressor 3 : Compressed air 4, 9 : Combustion chambers 5, 10 : Combustion fuels 6, 11 : Hot gases 7, 12 : Turbines 15-17, 21 : Regulating elements 20, 22-24 : Cooling air flows.
