Analiza nowoczesnych technik chłodzenia turbiny gazowej z zastosowanym spalaniem sekwencyjnym i ich wpływu na pracä elektrowni gazowo - parowej

In this article the impact of using different variants of the cooling blades in the gas turbine (closed steam cooling, open air cooling and closed air cooling) with the applied combustion sequence was presented. The structure of the combined cycle power plant with the different types of the expander cooling was presented. The analysis of the combined cycle units in a wide range of compression ratio in the compressor was conducted. Main operating characteristics of the analyzed units were performed.
