In this paper the development status and background of 350-MW China-made supercritical steam turbines are introduced.Through the study on the eight turbines that are put into operation,their technical performances are compared and summarized.The major factors affecting the heat consumption rate are analyzed in details and the technical measures to reduce the heat consumption rate are put forward.These measures have been applied to several such units with significant improvements,which can provide important references for the maintenance and retrofit of 350-MW super critical steam turbines.
