Abstract

The exergy and thermoeconomic analysis of components of power plants, refrigeration and polygeneration systems is presented and discussed to characterize the performance of such systems as well as to determine their products cost formation processes. Based on the general formulation of efficiency, presented in Chap. 2, the expressions of the exergy-based performance parameters of the components of these systems are derived. These concepts are applied to evaluate the electricity cost formation of a combined cycle power plant, and the comparative performance and production costs of steam and electricity of cogeneration plants configurations for chemical and dairy industries. Finally a comparative exergoeconomic study of trigeneration systems to produce electricity, steam, and chilled water is described and discussed.
