Exergetic and thermoeconomic analyses of diesel engine powered cogeneration: Part 1 – Formulations

摘要: This paper is part 1 of the study on energy, exergy, and exergoeconomic analysis diesel engine powered cogeneration (DEPC). Part presents formulation developed for such a comprehensive while 2 an application that considers actual power plant. Compression ignition among most efficient simple cycle generation plants where efficiencies are around 50%. The DEPC mostly preferred in regions natural gas not available or preferable because high unit prices. In this paper, plant considered with all associated components. Mass, exergy balances applied to each system component subsystem. Exergy balance formulations aimed yield destructions. Various based both energy methods performance assessment parameters defined components entire cost products, formation allocation within (i.e., analysis). analyses formulated here have significant importance obtain optimum marketing price product thermal systems maximize benefit and/or minimize cost.
