Question

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.

A steam turbine receives steam at 2000 kPa, 400°C, then it expands isentropically to 5 kPa and exhausts into a condenser. The condensate from the condenser is at 30°C and enters a feed heater where it is heated by bled steam at 300 kPa from the turbine. Its temperature is raised to the saturation temperature of the bled steam. The bled steam condensate is returned to the system after the feed heater. Calculate for a mass flow-rate of 1kg/s into the boiler: (a). mass flow-rate of the bled steam (b). the turbine power output
Steam at 2000 psia and 1000°F enters the high-pressure turbine of a reheat cycle and is expanded adiabatically and reversibly to 200 psia. The steam is then passed through the superheater, from where it exits at the 950°F temperature. The low-pressure turbine expands the steam reversibly and adiabatically to 1 psia. If 7 lbm/s of steam is used and the circulating pump is assumed to operate ideally, the power produced, the added heat rate, and the cycle efficiency are: a) 7049,76 hp ; 12124,5 Btu/s ; 42,2% b) 7400,77 hp ; 11553,7 Btu/s ; 45,1% c) 8350,08 hp ; 13089,6 Btu/s ; 49,8% d) 7944,76 hp ; 11834,2 Btu/s ; 47,6%

Saturated vapor Freon 12 refrigerant at 219.12 kPa leaves the evaporator and enters the compressor at -5 °C. The refrigerant leaves the condenser as saturated liquid at 25°C and enters the ex pansion valve at 22°C. Heat rejected from the condenser amount to 75 kW. The work to the compressor is 55.5 kJ/kg, while the heat lost from the compressor is 4.2 kJ/kg. If 1.15 kJ/kg of heat are lost in the piping between the compressor and condenser, cal culate the refrigeration capacity in tons.

The refrigerant is cooled in the condenser to 44°C and 1.16 MPa, and t is throttied to 0.21 MPa. Disregarding any heat transfer and pressure drops in the connecting lines between the components, show the cycle on a T-s diagram with respect to saturation lines, and determine (a) the rate of heat removal from the refrigerated space and the power input to the compressor, (b) the isentropic efficiency of the compressor, and (c) the COP of the refrigerator.

Calculate the mass flow rate through the boiler, the power produced by the turbine, the rate of heat supply in the boiler, and the thermal efficiency.
