In this paper, we introduce a new thermodynamic concept of greenizing energy systems and propose a new greenization factor which is defined as the amount of environmental impact reduction by the system greenized divided by the reference environmental impact for the original (reference) case. A...

A comprehensive exergy, exergoeconomic and environmental impact analysis and optimization is reported of several combined cycle power plants (CCPPs). In the first part, thermodynamic analyses based on energy and exergy of the CCPPs are performed, and the effect of supplementary firing on the...
