中文摘要: 针对汽轮机在滑参数停机时需冷却汽缸及法兰的问题,提出有效、快捷的冷却方法,以缩短检修工期和提高机组利用率.在机组滑停时,介绍了几种常见的冷却汽缸的汽源,并提出了新的冷却汽源及使用方法.
中文关键词: 滑参数停机  冷却汽源  选择  探讨
Abstract:When a steam turbine is in its smooth-parameter closing-down, casings and flanges should be gradually cooled. The present paper puts forward effective and fast cooling methods to cool the system. This approach demonstrates shortened inspection time and increased system availability. Some commonly-used cooling gas resources are introduced, a new gas resource and its applications are also presented.
