干熄焦烧损率的统计方法及烧损因素探讨

Statistic method for CDQ coke burning loss rate and discussion on burning loss factor

干熄焦烧损率的计算目前都采用碳平衡法,碳平衡法能确定干熄焦稳定运行时的烧损率,但进行生产统计时碳平衡法是不可取的。文中介绍了用干熄焦产汽率计算、统计干熄焦焦炭烧损的方法,该方法不需要进行碳排放量的测定,可随时进行统计计算,方便简单,精度能够满足生产统计需要,同时对干熄焦系统运行过程焦炭烧损的原因进行了分析和探讨。

The carbon balance method is adopted for the calculation of CDQ coke burning loss at present. The carbon balance method can determine the burning loss of CDQ coke during stable operation, but when the production statistic is carried out, it is not preferred. The carbon balance method for the calculation of CDQ coke burning loss and for CDQ steam generation rate statistic is described in the paper. The method does not need to do the carbon discharge measurement and can be used for statistic calculation at any time. It is simple and its accuracy can meet the requirement of production statistic, meanwhile the analysis and discussion on the causes of coke burning loss during the operation of CDQ system are carried out.
