Although the gas turbine combined cycle (GTCC) system has better environmental performance, it still emits pollution gases such as CO2 and NOx. It is reasonable necessary to add cost power production of GTCC system. Based on structure theory thermoeconomics, through pricing pollutants (considering costs NOx emission), thermoeconomic (ETC) model developed in this study, which achieves absolute i...

Use of Dedicated Mechanical Subcoolers gives rise to the need an optimisation process involving gas cooler pressure, activation and setpoint temperature values, subcooling degree subcooler size, with aim further improving energy efficiency while considering costs. In this paper a thermoeconomic analysis is performed on commercial refrigeration plant, at four climate conditions from warm hot, ti...
