浅谈汽轮机旁路供热调试过程中的问题与处理方法

Discussion on Problems and Solutions in the Adjustment of Steam Turbine Bypass Heating

针对热电联产机组的热电耦合无法满足电网调峰要求的情况,改造中常采用利用原有高、低压旁路系统进行供热的技术方案。对某机组高、低压旁路供热改造在调试过程中遇到的一些问题进行了分析,并对其处理的方法进行了阐述,为同行业内的相关调试提供一定借鉴与参考。

In view of the fact that the thermal-electric coupling of cogeneration units cannot meet the peak load regulation requirements of power grid,the technical scheme of using the original high and low pressure bypass system for heating is often adopted in the retrofit Some problems encountered in the commissioning process of the high and low pressure bypass heating transformation of a unit are analyzed,and the treatment methods are described,which provides reference for the relevant commissioning in the same industry.
