Performance evaluation of a mercury-steam combined-energy-generation system (MES)

Abstract

Summary In this study, exergy and thermo‐ecology–based performance analyses of a mercury‐steam combined–energy‐generation system are comprehensively presented. Performance characteristics such as net‐power output, net‐power density, exergy efficiency, exergy destruction, and ecological coefficient of performance have been obtained by developing a novel numerical model. The impacts of the pressures of open feed water heater and steam turbines, temperatures of mercury boiler, and mercury turbines on the performance characteristics have been investigated. The results indicated that the performance characteristics of the system have been remarkably affected by the pressure and temperature variations of the system components.

Multi-criteria performance optimization and analysis of a gas–steam combined power system

“…Isentropic temperature ratios: where k 1 is specific heat ratio dependent on C p1 and C v1 ; k 2 is specific heat ratio dependent on C p2 and C v2 ; k 1 and k 2 are also called isentropic exponents [79][80][81][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98]:…”

“…The exergetic efficiency of each system component is attained by using the following equations [95][96][97][98][99][100].…”

“…Since the 1970s, Finite Time Thermodynamics (FTT) has made great progress in physics and engineering fields [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Many scholars have researched the optimal performances of thermal and chemical processes and cycles [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. A great deal of work has been performed for the optimal configurations of thermal and chemical processes and cycles [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ], including heat transfer, mass transfer, heat and mass transfer, ...…”
