Analyses And Study On The Thermal Economy In 600MW Ultra Super Critical Unit Of Power Plant

In the paper, analyze and study the thermal power systems econmics of the 600MW ultra-supercritical unit assembly in Yingkou power plant, and compare it with 600MW domestic assemblies to find out the difference of the economical level. After researching the part thermal systems and equipments include turbine trunk, steam leakage and receiving systems, heaters, drain cooler and steam cooler etc, and computing the efficiency of the systems and equipments, find out the better choice of the imported assemblies than the domestic assemblies in parameter and the disfigurements in design and making. Based on the above, point out the measure to progress them. According to the analysis, we can get some measures to increase the economical level of the system and save more energy. At the same time, discuss ultra-supercritical development of technology and superiority and analyse the problem of choosing the type , parameter and thermodynamic system optimization , have been that our country absorbs the advanced technology provides a reference.
