Exergoeconomic Analysis of Gas Turbine Power Plants

Abstract

The main purpose of this paper is to apply the thermoeconomics concepts to a projected gas turbine system, which aims at providing the electrical demand of an industrial district sited in Mahshahr, Iran. A unit exergy cost is assigned to each disaggregated exergy in the streams at any state. This methodology permits us to obtain a set of equations for the unit costs of the system and to each junction. The monetary evaluations of various exergy costs are obtained by solving the set of equations. The comparison analysis between typical exergy-costing methodologies was also evaluated.
