英文摘要: Abstract(#br)The main objective of the presentstudy is to determine whether the thermodynamic efficiency of a modern combined cycle power plant (CCPP) with steam reheating can be increased when using designs both with and without CO 2 separation and compression installations. The relatively high costs of a steam cycle compared to a gas turbine (GT) have motivated the present direction of efficiency research in this area. Therefore, in all systems analyzed in this work, the same structure of heat recovery steam generator (HRSG) was assumed, producing fresh and secondary steam, with the parameters 600 °C/18 MPa and 600 °C/4 MPa, respectively, and a constant GT exhaust gas temperature of 630 °C. A methodology for modeling the operation of a GT within a wide range of compression ratios β (10...
