【摘要】 本文对日照350MW机组热力系统热经济性进行了分析研究，并和国产300MW机组的热经济性进行比较，找出热经济性的差异。对局部热力设备及热力系统进行分析研究，包括:加热器设备、漏汽及回收系统、低加疏水系统、主、再热蒸汽系统以及凝汽器等部位；并计算汽轮机本体高、中、低压缸效率，借此着重对汽轮机通流部分进行了剖析，找出国外进口机组动、静叶栅、叶型的选择比国产机组先进性以及国产机组在通流部分设计和制造中的诸多缺陷，并且指出了改进的方向，为机组提高热经济性、节能降耗奠定了理论基础。更多还原

【Abstract】 In the paper, analyze and study the thermal power systems economics of the 350MW assembly in RiZhao power plant, and compare it with 300MW domestic assemblies to find out the difference of the economical level. After researching the part thermal equipments and systems include heaters, steam leakage and receiving systems, low pressure drain system etc, and computing the efficiency of the systems, 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 systems and save more energy.
