Abstract

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, Ahead of Print.
A combined cycle integrating a gas turbine (GT) with supercritical carbon dioxide (sCO2) and organic Rankine cycles (ORC) can recover waste heat from the GT’s flue gas. To evaluate the exergoeconomic performance of this GT/sCO2/ORC system, both ...
