While steam power cycles provide much of the electricity that powers the United States, not all the thermal energy used to generate the steam comes from burning fossil fuels. Below is a high-level schematic of a concentrated solar power (CSP) plant that uses a sodium-/potassium-nitrate molten salt to absorb solar thermal energy which is then transferred to steam to run a superheat Rankine cycle. Parabolic mirrors (receivers) concentrate solar energy onto pipes carrying the molten salt. As the molten salt flows through these tubes, it absorbs the reflected solar energy and eventually transfers this energy to steam in a heat exchanger (boiler). For your ensuing analysis, you may assume that the boiler and condenser operate isobarically.

Compare the thermal efficiency and turbine-exit quality (temperature if superheated) at the condenser pressure for a simple Rankine cycle and the reheat cycle when the boiler pressure is 5 MPa, the boiler exit temperature is 500°C, and the condenser pressure is 20 kPa. The reheat takes place at 0.5 MPa and the steam leaves the reheater at 500°C. (Enthalpies are in KJ/kg.) Without the reheater, the heat added is: The enthalpy entering the condenser is: The net Work is: The enthalpy entering the reheater is: Without the reheater, the net Work is:
ercise 6 6.1 A surface condenser is fitted with separate air and condensate outlets. A portion of the cooling surface is screened from the incoming steam and the air is passes over these screened tubes to the air extraction and becomes cooled below the condensate temperature. The condenser receives 20 000kg/hr of dry saturated steam at 36.2°C. At the condensate outlet the temperature is 34.6°C TK and at the air extraction the temperature is 29°C.
