Abstract: Systems and methods axe disclosed herein that generally involve a double pinch criterion for optimization of regenerative Rankine cycles. In some embodiments, operating variables such as bleed extraction pressure and bleed flow rate are selected such that a double pinch is obtained in a feedwater heater, thereby improving the efficiency of the Rankine cycle. In particular, a first pinch point is obtained at the onset of condensation of the bleed and a second pinch point is obtained at the exit of the bleed from the feedwater heater. The minimal approach temperature at the first pinch point can be approximately equal to the minimal approach temperature at the second pinch point. Systems that employ regenerative Rankine cycles, methods of operating such systems, and methods of optimizing the operation of such systems are disclosed herein in connection with the double pinch criterion.

Abstract: A plant (10, 110) for the production of electric energy comprises a fuel boiler (11) in which a fluid is heated in order to produce steam, a turbine (15) which is connected to an electric generator (16) and to which said steam is conveyed, and a condenser unit (19) which re-condenses the fluid output from the turbine so that it may be conveyed back to the steam generator. The return fluid along the path from the condenser unit (19) to the boiler passes through a preheating unit (22) which receives heat from the turbine steam bleed-offs (23) and from a thermodynamic solar field (25). By making suitable use of the heat produced by the solar field (25) and contained in the heat-carrier fluid which passes through it, it is possible to increase the overall efficiency of the plant (10, 110). Furthermore, advantageously, the heat-carrier fluid which passes through the thermodynamic solar field receives heat from the fuel boiler via a suitable exchanger (32) which allows an increase in the productivity of the solar field itself and, moreover, uses the residual heat of the main plant which otherwise would be lost.
