英文摘要: Abstract(#br)This paper presents a methodology to clearly identify energy benefits (in terms of power and efficiency) resulting from the use heat from gas turbine steam cooling and heat from cooling air. These potential benefits are evaluated in terms of the characteristics of combined cycle power plants in a wide range of pressure ratios β = 10 ÷ 100. Calculations were made for four variants (optimistic and conservative), differing in terms of the performance characteristics of the compressor and turbine isentropic efficiency as a function of β and the permissible temperature of the expander blades in the gas turbine. The steam part of the power plant in question is composed of a classical steam cycle with a triple-pressure subcritical heat recovery steam generator (HRSG) with reheating,...
