GASTURBINE MIT GEREGELTER LUFTKÜHLUNG

摘要

The gas turbine (20) has compressor (11) to compress combustion air. A portion of compressed combustion air is supplied to combustion chamber (13) and a fuel is burned in the chamber. A turbine is placed in downstream side of the chamber, and hot combustion gas from the chamber is expanded in turbine to perform work. A cooling air cooler (18) to which the other portion of the compressed combustion air is branched off and is cooled. Another turbine that supplied with cooling air is configured to lower the pressure of the cooling air.
