The Analysis of Thermal Efficiency of CCGT with Back - Pressure via the Methods of Small-Deflection

Abstract

Presents the results of studying the influence of efficiency gas turbine and steam section of CCGT on the thermal efficiency of combined-cycle plant with back-pressure based on a powerful high-temperature gas turbine. To assess the impact of selected parameters was made analysis by method of small-deflection. The advantages of one-circuit combined-cycle in comparison with more complex schemes. According to the research results, have been made corresponding conclusions.
