摘要:

凝汽器是抽汽冷凝式汽轮机凝气系统的核心设备。凝气系统在正常操作时为负压,凝汽器工作状态的变化直接影响汽轮机的工作效率。对天津石化200 kt/a乙烯装置裂解气压缩机蒸汽透平的凝汽器在线清理消漏过程进行了介绍,并对凝汽器的使用、在线监测等不足之处提出了整改意见。

Abstract:

Condenser is the core equipment of condensate system of extraction condensing steam turbine. The condensate system is under negative pressure during normal operation, and the change of working state of condenser directly affects the working efficiency of steam turbine. In this paper, the on-line cleaning and leakage elimination process of the condenser in steam turbine of cracking gas compressor in the 200 kt/a ethylene plant at SINOPEC Tianjin Company is introduced, and some improvement suggestions are put forward for on-line monitoring and other deficiencies.

Key words: steam turbine, condenser, internal leakage
