摘　　要：汽轮机通流部分是工质在汽轮机本体中流动做功所经过的汽轮机部件的总称。汽轮机通流部件主要包括截流调节装置、汽轮机静叶栅和动叶片、汽封和轴封及其它辅助装置。汽轮机通流部分技术改造是提高机组效率、节能降耗的有效措施。本文介绍了自2009年以来某地区汽轮机组改造的技术特点、原则和内容,结合现场性能考核试验对改造效果进行了分析,并提出相应的改进措施,为国内同类型机组的改造和试验提供了借鉴。Turbine flow section is the general term of components that the steam flows through when acting in the steam turbine.Turbine flow section including closure adjustment device,static and dynamic turbine blade,steam seal and shaft seal and other assist device.The transformation of turbine flow section is the effective measures to improve the unit efficiency and energy saving.This article introduces the transformation of technical characteristics,principles and contents on a steam turbine unit in the period since 2009,analyses the effect of transformation by on-site performance test,proposes improvement measures,and provides reference for the transformation and test of the same type units.
