In sodium cooled reactors and high temperature gas cooled reactors(HTR),helical coil steam generator has been extensively employed because of it's advantage in tight structure、good heat transfer and small size. Based on the experimental study for flow induced helical tube bundles vibration,this paper advanced an empirical correlation which predicted the critical flow velocity of fluid elastic instability,and suggested an engineering design guideline,which included the experi-mental data obtained in...

At the air duct of Xi'an Jiaotong University, which was established on the design parameters of steam generator for the 200 MW high temperature gas cooled reactor (HTR), the experimental study on the behavior of helical tube bundles vibration in steam generator, which was induced by low density cross flow, has been done. The problem such as the critical flow velocity at which fluid elastic instability phenomenon begin to occur, the reciprocal action on neighboring tubes in different helical radius, and that in the same helical radius etc., has been discussed in detail. The results provide bases for designing helium steam generator for HTR, and bases to advance theoretical study on flow induced helical tube bundles vibration too.

在西安交通大学风洞台架上,针对200MW高温气冷堆蒸汽发生器设计参数所建立的实验模型,研究了蒸汽发生器中螺旋管管束在横向低密度流体冲刷下的振动行为。针对发生流体弹性不稳定现象时的临界流速;不同螺旋半径上相邻管的相互影响;同一螺旋半径上、下游管的相互影响等问题作了讨论。获得的结果对高温气冷堆氦气蒸汽发生器的设计提供了依据,同时亦为螺旋管束的诱发振动理论计算和理论模型的建立提供实验依据。

There were still some problems although repaired it quite a few times. The production didn't run normally. By means of checking leakage location, it was analyzed and calculated carefully from the aspects of medium corrosion, vibration and erosion.

Three months after the installment of epoxy ethane desorption tower's reboiler, leakage was found soon in glycol unit of a chemical plant. There were still some problems although repaired it quite a few times. The production didn't run normally. By means of checking leakage location, it was analyzed and calculated carefully from the aspects of medium corrosion, vibration and erosion. The result shows that there are some self - design faults causing the tube bundle vibration, whereas it is the tube bundle vibration and liquid erosion that are main reason of reboiler leakage. So the problem about tube bundle vibration should be paid a close attention in heat exchanger design and leakage analysis. The reconstruction by using the improved measure presented in the paper had a satisfying effect, which keeps the operation period longer.

某化工厂乙二醇装置环氧乙烷解吸塔再沸器安装投用3个月后便发现了泄漏,经多次修复,问题均未得到彻底解决,严重制约着生产的顺利进行。通过对再沸器泄漏部位的检查,并从介质腐蚀、振动及介质冲蚀3个方面进行详细地分析、计算。结果表明,再沸器自身设计缺陷是引发管束振动的原因,而管束振动和介质冲蚀正是该再沸器频繁泄漏的主要原因。因此,管束振动问题在换热器设计及换热器泄漏分析中应引起足够的重视。同时根据改进措施对其进行改造,取得了较好的效果,保证了再沸器的长周期运行。
