Research of Closed Brayton Cycle Solar Thermal Power System

Refrigerant phase-change closed-Brayton-Cycle With Intercooling, Reheating and Regeneration Solar Thermal Power System are proposed. The refrigerant would deliver heat from the solar furnace at temperatures between 700°C and 850°C to a closed multireheat Bray-ton power cycle using NH3 as the working Fluid. Finite-time thermodynamics was applied to analyze the characteristic of the cycle power output the efficiency and of Intercooling, Reheating and Regeneration Solar Thermal Power System.
