| Abstract: | This paper introduces the characteristics of steam distribution mechanism of supercritical 600 MW turbine units brought in Hitachi technology produced by Dongfang Turbine Company Limited and points out that restriction loss influences the economy of unit operation within low and medium load.Aiming to solve this problem,the paper proposes to improve valve order and configuration and optimize operation.Practical operation proves that the economy of turbine unit is apparently enhanced. |
