A 1000MW ultra-supercritical secondary reheat unit Energy consumption analysis of thermodynamic system

Taking the thermodynamic system of a 1000MW ultra-supercritical secondary reheating unit as research object, modeling energy consumption analysis was carried out, and spatial distribution determined, so to provide scientific basis for operation optimization energy-saving transformation unit. The results show that: Boiler is one largest equipment factory irreversible loss, make up loss by 85.1% total system, although number its external not big but internal very big, high grade energy, steam turbine cold source large high, only 2.32% system.
