摘　　要：本文利用釜式再沸器壳侧循环流动与管束传热的分格模型，进行了管束中不同管列循环流速的模拟计算．考察了管束直径、液面高度、管束排布方式、管间距和加热方式对循环流速的影响．并对计算结果进行了分析．Circulation flow velocity in different tube arrays of tube bundles is calculaled by using a grid model of circulation flow and heat transfer outside a tube bundle in a kettle reboiler.Examinations are made of the influence on circulation flow velocity exerted by the tube bundle diameter,height of liquid level above tube bundles,arrangement of tube bundles,tube pitch and heated forms.Calculated results are analyzed.
