EXERGOECONOMIC ANALYSIS OF A DIESEL ENGINE

17th Brazilian Congress of Thermal Sciences and Engineering, 2018
The method of producing power from diesel engines despite being created a long time is still quite used these days, and pollutants formation including their emission are considered one of the major sources of air pollution. This study reports the effects of the engine load on the specific cost per exergy unit of electricity.

An exergoeconomic approach for retrofit of fractionating systems

Energy, 2002
Abstract Based on a three-link model, this paper presents a multi-objective retrofit optimization algorithm that simultaneously takes into account capacity expansions and uses of energy. This approach was successfully applied to retrofit an aromatic fractionation unit.

Exergoeconomic evaluation of a geothermal power plant

International Journal of Exergy, 2014
In this study, exergy and exergoeconomic analyses of the Dora II geothermal power plant (DGPP) with 9.5 MW net power output are carried out by using real thermodynamic and cost data. The exergetic efficiency of this plant is calculated to be 29.6%. The highest exergy destruction rate among the DGPP components occurs in the cooling towers followed by ...

An Approach of Exergoeconomic Analysis of Thermal Systems

Advanced Energy Systems, 1997
Abstract A new approach of the combination of exergetic and economic analysis for the complex energy system has been proposed, that is, a general exergy and the corresponding cost balance equation which can be applied to any component of thermal system have been formulated.

EXERGEOCONOMIC ANALYSIS OF THERMAL SYSTEMS

2007
Publisher Summary In the analysis and design of energy systems, techniques are often used which combine scientific disciplines (mainly thermodynamics) with economic disciplines (mainly cost accounting) to achieve optimum designs. This chapter presents a brief summary of existing analysis techniques, which integrate exergy and economics.
