ABSTRACT:
A cooling steam system for a steam cooled gas turbine is configured such that a main stream of exhaust from a high pressure turbine is branched from a line leading to a reheater, and supplied as cooling steam for a high temperature moving blade and a high temperature stationary blade of the gas turbine, and the cooling steam is then recovered into an inlet area or an intermediate area of the reheater; whereby the bottoming side and the steam cooled side can be operated under preferred conditions without adverse influence on the bottoming side.
