| Abstract: | To solve the problem of high energy consumption in a 600 MW supercritical turbine unit, due to low flow efficiency of the steam turbine, high consumption rate of the reheater attemperating water, and large terminal temperature difference of the condenser at low load, etc., thermal performance tests were performed to the unit before overhaul, so as to analyze the problems existing in flow passage and auxiliary equipment of the steam turbine, as well as the resulted influences upon the turbine performance, thus providing reference for design of power plant energy conservation. |
