Fundamentals of exergy analysis

Abstract

Conservation laws are important tools in analysis of thermal processes. In engineering practice, substance conservation law and energy conservation law are commonly used. Exergy analysis based on first and second law of thermodynamics are still rarely applied in engineering and industrial practices. Demonstration of its potential to examine the imperfection of thermodynamic processes, evaluation of efficiency of resources transformation as well as to measure ecological effects is one of the main aims of this book. Thus, in this section, fundamentals of first, second law and exergy analysis are presented. In Chap. 3, two examples illustrating the rules of exergy balances are included. They present energy and exergy evaluation of steam boiler and steam heat-and-power plant (CHP).
