A solar-power-tower plant is considered for Alabama, Birmingham. Heliostats with a total area of 400,000 f are to be used to reflect solar radiation into a receiver. When the solar iradiation is 250 Btu/h.fr, steam is produced at 160 psia and 600 °F at a rate of 15 lb m/s. This steam is expanded in a turbine to 2 psia pressure. The isentrople efficiency of the turbine is 88 percent. (a) Find the power output in kW and the thermal efficiency of the plant under these operating conditions.
