Thermodynamic analysis of a thermal cycle of supercritical power plant

Elsner W., Kowalczyk Ł., Niegodajew P., Drobniak S.

Mechanics and Mechanical Engineering

2011

Vol. 15, nr 3

217-225

The study presented in this paper deals with the analysis of operating conditions of a modern supercritical power plant. The 460 MW reference thermal cycle, which is based on the Łagisza supercritical, coal fired power plant was selected for this study. The thermodynamic analysis was performed with the use of the industrial software package IPSEpro, designed for power plant engineering. The main objective was to demonstrate the role of supercritical parameters in enhancing the efficiency of the thermodynamic process. It was done among the others by the comparative analysis of two thermal cycles, one working with standard and the other with supercritical parameters. Apart from nominal operating conditions part load operation was analyzed.
