- Exergoeconomic performance optimization for an endoreversible regenerative gas turbine closed-cycle cogeneration plant Guisheng Tao Lingen Chen Fengrui Sun Física, Astronomía y Matemáticas profit rate Finite time thermodynamics exergoeconomic performance gas turbine cycle cogeneration plant Finite time exergoeconomic performance of an endoreversible regenerative gas turbine closed-cycle cogeneration plant coupled to constant temperature heat reservoirs is investigated. The analytical formulae about profit rate and exergy efficiency of the cogeneration plant with the heat resistance losses in the hot-, cold- and consumer-side heat exchangers and the regenerator are deduced, respectively. By means of numerical calculations, the heat conductance allocation among the four heat exchangers and pressure ratio of the compressor are optimized by taking the maximum profit rate as the objective. The characteristic of optimal dimensionless profit rate versus corresponding exergy efficiency is investigated and the effects of design parameters on optimal performance of the cogeneration plant are also analyzed. The results show that there exist a sole group of optimal heat conductance allocations among the four heat exchangers and an optimal pressure ratio of the compressor which lead to the maximum dimensionless profit rate, and there exists an optimal consumer-side temperature which leads to double-maximum dimensionless profit rate. 2009 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57013232006 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
