Exergetic sustainability analysis of a naphtha-based combined cycle power plant (CCPP)
View through CrossRef
Abstract
In today’s scenario ensuring sustainability of energy system particularly in the field of power generation is a major concern, and in this regard exergy analysis is widely accepted tool. For this purpose, first a comprehensive performance is carried out between two gas turbine plants i.e. GT2 (case I) and GT1 (case II) using various exergy performance parameters. Further a comprehensive performance evaluation is carried out between three cases; GT2 (case I), GT1 (case II) and CCPP (case III) using different sustainability indicators such as exergy efficiency, waste exergy ratio, exergy destruction factor and recoverable exergy ratio. Results demonstrate that exergetic sustainability index of combined cycle power plant (CCPP) is 0.45 when compared with GT2 (0.29) and GT1 (0.28). The increased sustainability index is because of the incorporation of a bottoming cycle, which ultimately decreases waste exergy ratio and leads to an increase in exergy efficiency and sustainability index of CCPP.
