Combining the first law of thermodynamics with the second law of thermodynamics

the heat transfer analysis and exergy analysis of thermal power generation system using steam directly produced from parabolic trough type solar energy facility have been carried out.Taking INDITEP project as example

the heat balance calculation and exergy banlance calculation of the system have been performed

obtaining the thermal efficiency and exergy efficiency of every part and the entire system.The exergy efficiency of heat collector is lower than its thermal efficiency

while the exergy efficiency in Rankine cycle of water/steam is higher than its thermal efficiency.
