Abstract

A simplified analysis is given for determination of the overall efficiency of a recuperative combined gas turbine/steam power plant, with and without feed heating. It is shown that for prescribed state properties in the (higher) gas turbine plant and specified pressures in the (lower) steam cycle, feed heating leads to reduced plant overall efficiency. However, if the temperature of the gas leaving the heat-recovery steam generator is limited (to avoid corrosion in the heat-recovery steam generator) then the disadvantage resulting from the introduction of feed heating is small.
