The efficiency of utilizing coal in China is low.One of the most important reasons is that most of the coal users cannot use the high quality coal to the reasonable purpose.Therefore,assorting and utilizing coal becomes more and more arresting.In this paper,the dynamically admeasuring coal was studied on.On the establishment of mathematical models,the optimization result was numerated through illustrating the process of dynamically admeasuring coal. With this method,the cost of dynamically admeasuring coal could be reduced to the lowest level,and the problem of reducing the heat value during utilizing the low-sulfur coal would be resolved.Also the condition of the coal combustion would be ameliorated.Comparing with combusting the normal coal,10% coal could be saved,and the soot value could be reduced more than 60%,which is good for both improving efficiency and protecting the environment.
