摘要
初步探讨了丁二烯抽提装置第一汽提塔再沸器ＥＡ—１０８自１９９４年以来频繁地发生泄漏的原因，结合诱导振动理论进行了振动分析计算，当负荷为１５．５ｔ／ｈ时，只用一台ＥＡ—１０８，壳程中蒸汽的流速达到诱发管子振动的临界流速，极易发生振动而泄漏，改用两台再沸器，大大减小发生振动的可能性。
A discussion on the reason that EA 108 reboiler at the butadiene-extraction plant has been leaked frequently since 1994and the possibility caused tube vibration was analyzed and calculated according to the theory of inducing vibration.Tabes vibrate easily when the duty is 15.5t/h and one reboiler is used only.Vibration is decreased greatly when two reboiler are used.
