300 MW供热汽轮机连通管的改造

摘要

介绍了300 MW供热汽轮机组的构造及功能，阐述了中低压连通管的运行情况，探讨了“一二一”型中低压连通管晃动原因及对策，提出了中低压连通管的改造方案。%This paper introduces the structure and functions of 300 MW heat supply steam turbine, expounds the running status of the meddle and low pressure communicating pipes, probes into the reasons of the jittering of 121-type meddle and low pressure communicating pipes and countermeasures, and puts forward the transformation scheme of meddle and low pressure communicating pipes.
