带表面式凝汽器间接空冷系统散热器循环水管束冻裂原因分析
摘要
带表面式凝汽器的间接空冷系统在寒冷地区冬季散热器管束冻裂是较为突出的问题
对此
着重从冻结机理入手进行分析
认为中间隔板短路是造成管束冻裂的主要原因。提出了相应的改进技术措施。
Abstract
Frost-crack of the radiator tube bundles during the period of winter in frigid area is a comparatively prominent problem for indirect air-cooled system with suface condenser
a cause analysis for the said problem has been carried out
taking emphatically the freeze-up mechanism as the point of departure. It is considered from said analysis that the short-circuit of intermediate partition plate is the main cause resulting in frost-crack of the said tube bundles
and corresponding technical measures for improvements have been put forward.
