DESIGN BY OPTIMUM METHOD FOR THE 11TH STAGE'S FLOW PASSAGE OF 18MW STEAM TURBINE MADE IN CHINA

Abstract

Abstract: After improving the design of the 11th stage’s flow passage of 18MW steam turbine made by Nanjing Turbine and Electric Machinery, Co. Ltd. , the aerodynamic performance of this stage is improved greatly. As a result, the efficiency of this stage is raised notably. It provides a valuable experience for the improvement of middle and small turbomachinery.
