Question

Question 12 10 points Save Answ The following diagram shows collectors have an approximate efficiency of 60%. Efficiency of the steam-turbine is about 50%. The energy conversion efficiency of the generator is 90%. Calculate other losses ( solar thermal power system. The average daily overall plant (solar-to-electric) efficiency is 20%. Solar trough ) % that are unaccounted for in the system. Solar Field Solar Superheater Steam Turbine Hot Salt Tank Generator Boiler (optional) Condenser IOil-to-Salt Heat Exchanger Deaerator Steam Generator Fuel Feedwater Heaters Solar Preheater Solar Reheater Cold Salt Tank Expansion Vessel
