Abstract
The paper presents influence of the gas turbine steam cooling on the combined cycle power plant efficiency. Heat of the cooling steam was used in the steam cycle to improve the work characteristics of the power plant. The structure of the unit with the applied steam cooling was presented. For the expander cooling, the steam was charged from bleeders between the high-pressure steam turbine and medium part. Analysis of the impact the steam cooling on the efficiency of the combined cycle gas turbine was conducted in wide range of the pressure ratio in the air compressor. The main characteristics of the analyzed combined cycle unit were performed. The ecological characteristic of the analyzed unit was presented.
