摘要
提出目前国内的循环流化床锅炉在性能上存在两大问题：一是不能定量地确定循环倍率，导致燃烧性能的计算不准确；二是不准确的，甚至不正确的友平衡计算导致传热性能的计算不准确。并从灰平衡的基本要素出发，对循环倍率和友平衡的计算方法进行了探讨。阐述了正确地确定循环流化床锅炉的循环倍率和灰平衡计算方法不仅是必须的，而且是迫切的。
Nowadays,there are two main problems of domestic CFB boilers in prop-erties. First,as the circulating ratio can't be quantified,the caleulation of combus-tion performance is inexact;Second,as the calculation of ash balancing is not exactor right,the calculation of heat transmission performance is inaccurate- From thebasic factors of the ash balancing,the calculation of the circulating ratio and ashbalancing is inquired into,then the calculation of the circulaling ratio and ash bal-ancing of CFB boiIers is right established which is both necessary and pressing.
