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

Abstract

Abstract. Presents the results of studying the influence of efficiency gas turbine and steam section of CCGT on the thermal efficiency of combinedcycle 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.

Effect of external conditions and steam parameters on performance of combined-cycle power plants with back-pressure steam turbine

“…If no additional electrical power is needed, the initial vapor pressure can be decreased to 5 MPa. The study complements the results obtained in [8].…”
