The potential execution of optimized gas-steam combined cycles built around the latest generation
gas turbine motors is analyzed, by implies of energy/exergy equalizations. The options here
considered are the warm gas turbine and the H-series with closed-loop
steam edge cooling.Recreations of execution were run employing a well-tested Modular
Code created at the Office of Vitality Designing of Florence and subsequently improved
to incorporate the calculation of exergy pulverization of all sorts (warm transfer, friction, blending,
and chemical irreversibilities). The edge cooling process is analyzed in detail because it is
recognized to be of capital significance for execution optimization. The distributions of the relative
exergy devastation for the two solutions both competent of achieving energy/exergy
efficiencies within the extend of 60 percent are compared and the potential
for advancement is examined
