空冷排气管道主要技术问题分析

Analysis on the Main Technical Issues of Exhausted Steam Pipes for Direct Air-Cooled System

随着我国空冷电站的快速发展及运行经验的不断积累,直接空冷系统已逐步实现国内自主设计。排汽管道作为空冷系统的重要组成部分,其管道系统优化设计对提高电厂运行的可靠性和安全性具有重要作用。为此,对空冷排气管道的主要技术问题进行了分析,为直接空冷系统排气管道的自主化设计提供参考。

With the rapid development of the air-cooled power plants in our country and the continuedaccumulation of operating experiences, the self-design of direct air-cooled system has been being graduallyachieved. The exhausted steam pipe is all important part of the air-cooled system and its design optimization playsa key role in improving the reliability and safety of the power plant operation. For this reason, the main tectmical issues of exhausted steam pipe for air-cooled systemare analyzed, which provides reference for the self-design of exhausted steam pipe in the direct air-cooled system.
