METHOD AND APPARATUS FOR COOLING A TURBINE WITH COMPRESSED COOLING AIR FROM AN AUXILIARY COMPRESSOR SYSTEM

摘要

A combustion turbine system (10) is provided with compressed cooling air (50) by an auxiliary air compressor (54) system. The combustion turbine system (10) has a system air compressor (12), a combustor (14) and a turbine (16). The auxiliary air compressor (59) system receives an air stream and produces a compressed cooling air stream (50) therefrom. The cooling air stream (50) is then directed to the combustion turbine system (10) and is used to cool the turbine (16).
