Energy-Saving Analysis on Thermal System in 600MW Supercritical Coal-Fired Power Plants

Abstract

High-efficiency, energy-saving and environmentally friendly supercritical thermal power units are gradually becoming main stream in China. In this paper, an advanced energy system analysis method, specific consumption analysis, is used to examine the performance of 600MW supercritical coal-fired power plants and to identify and evaluate the specific consumption accruals. Moreover, the specific consumption analysis provides a detailed energy saving-effect of feed-water heating system at the load of 100%, 75% and 50%. The results are of great significance for the energy-saving of supercritical coal-fired power plants.
