moisture of the saturated vapor at the last stage of steam turbine. Integration
of a bottoming ORC with regenerative gas turbines or gas turbines with a
relatively high pressure ratio is practically viable [5].
A schematic of an ORC with regeneration is shown in Fig. 8.13.
A T-s diagram of the cycle operating with R600 as the working fluid is
depicted in Fig. 8.14. A hot fluid with a given temperature and flowrate
enters the evaporator where the preheated working fluid is further heated
up to a few degrees above its evaporation temperature. The hot fluid with
