Inlet cooling is effective for mitigating the decrease in gas turbine performance during hot and humid summer periods when electrical power demands peak, and steam injection, using steam raised from the turbine exhaust gases in a heat recovery steam generator, is an effective technique for...

This paper presents the exergoeconomic analysis of a novel process generating electric energy and hydrogen. Coal and high-temperature heat are used as input energy to the process. The process is a true “zero-emission process” because (a) no NOX is formed during coal combustion with sulfuric...

In this study an exergy and exergoeconomic evaluation of a heat supply system paradigm of Japan and a district heating system (DHS) is conducted from a single user perspective, providing cost-based information on the systems inefficiencies and improvement potential. A heat supply system of a...

Biomass can be converted thermo- and bio-chemically to solid, liquid and gaseous biofuels. In this paper, energy, exergy and exergoeconomic analyses are applied to a biomass integrated post-firing combined-cycle power plant. The energy and exergy efficiencies of the cycle are found to be...
