摘　　要：竖式预热器是煅烧活性石灰的主机设备之一,在预热器的设计过程中,是否需要采用偏心设计以及采用偏心设计后会对竖式预热器内部气流产生什么样的影响,是困扰设计者的一个问题。本文采用流体计算软件计算了不同偏心距数值下预热器的气流分配,得到了预热器偏心距设计对内部流场的影响,为以后预热器的设计提供了参考。The vertical preheater is one of the host device of active lime calcination. In the design process of the preheater,It is a problem that whether to use eccentric design and what is the influence on internal airflow if the design adopted. The problem have plagued designers for a long time. In this paper,the flow distribution of the preheater is calculated by the fluid calculation software,and got the influence of the eccentric design to preheater,which provides a reference for the designer of preheater.
