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.

In a Rankine cycle, saturated liquid water at 1 bar is compressed isentropically to 150 bar.First by heating in a boiler, and then by superheating at constant pressure of 150 bar, thewater substance is brought to 750 K. After adiabatic reversible expansion in a turbine to 1bar, it is then cooled in a condenser to a saturated liquid. Using steam tables, what is thethermal efficiency of the cycle?

A geothermal resource/aquifer has been tested and confirmed to continuously produce saturated liquid water at 230°C. It is desired to construct a 60 MW geothermal power plant, which will utilize this resource. Two designs are proposed: a) a single flash unit and b) a dual-flash unit. A nearby cooling pond may supply sufficient cooling water to keep the condenser of the plant at 40°C. For the two types of units under consideration calculate: a) The total amount of steam that needs to be produced. b) The total amount of water the wells must provide. c) If each well produces 60 kg/s of water, what is the number of wells that must be drilled?
Power generation using steam is one of the most common method which can be found around the world. In these type of power plants, steam goes through a basic thermodynamic cycle called Rankine cycle which is shown in the following figure. Steam flow Boiler Qin Pump Wout Win Condenser For the proper operation of the cycle, water should be pumped to the boiler using pump which required work input (Wn) to the cycle. Heat energy should be supplied to the boiler (Qin) to generate steam and then high pressure steam is fed to the turbine. By extracting the energy from high pressure steam, turbine is producing work output (Wout)- Because of this, the steam pressure is reduced and low pressure steam is flowing into the condenser. Condenser removes heat energy from steam further (Qout) and steam is converted into liquid water. The liquid water can be pumped into the boiler again and the cycle continues. Performance of a Ranking cycle can be evaluated by using thermal efficiency (neh)which is…
