Abstract:

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.
