Exergoeconomic analysis of Figueira thermal power plant

This work approaches general aspects of the analysis of the Figueira thermal power plant with the objectives of knowing its actual operating condition and evaluating the costs of internal flows. The application of the Second Law of Thermodynamics through the systematic use of the exergy concept and the Theory of Exergetic Costs were the basic tools for this analysis. The conducted study was preceded by some preparatory activities among which the main ones are: determination of actual productive structure of the plant; implementing the proper measurement instruments in strategically selected spots and evaluation of the plant performance by testing it in accordance to standard norm codes. In the work presented here these preparatory steps are described in detail. Once the preparatory steps were taken, the exergetic and thermoeconomic analyses of the plant were performed. These analyses allowed the identification of the main plant inefficiency sources as well as the exergetic and economic costs of every internal flow of the plant.
