Abstract

Abstract: The practice operating date and design index of the low pressure cylinder of 330MW steam turbine generator was compared for the Ningxia Shizuishan Power Generation Corporation Limited of China Guodian Corporation. Defects of gangway for the low pressure cylinder exhaust system was finded.The modification measure was installed the uniform flow device in the low pressure cylinder exhaust passageway was adopted. The problem of low vacuum of the generation unit was solved.This modification measure have been favorable effects and economic marked beneficial result.

Key words: steam turbine generator, low pressure cylinder, exhaust system, vacuum, modification, economics
