The rapid development of the city and the speeding of the industrialization advancement make the quantity of sewage sludge increasing. These factors cause great trouble to our living environment. In order to reduce the influence of sewage sludge to the living environment, many learners and experts pay close attention to it.First, in the study of the characteristic on combustion of sewage sludge, the basic combustion of sewage sludge is analyzed. The process of weightlessness of sewage sludge is comprised by four parts. Besides these, the characteristic of sewage sludge is analyzed. The dynamic parameters are obtained by using the differential method.Second, the basic combustion situation of coal is explained. And the characteristic on combustion of coal is analyzed. The integral method is used to get the dynamic parameters of coal.The next, the method of thermogravimetric analysis of sewage sludge is studied, and the weightlessness process of sewage sludge is divided into four parts, without considering the water, the other three processes is corresponding to three parallel reactions. The kinetic parameters can be obtained by using multiple. As a result, the standardization curve of the weightlessness can be obtained.The last, the characteristic on combustion of sewage sludge and coal and three kinds of proportion between them are researched. The result shows that the comprehensive combustion performance of the mixture is good. The burning of mixture can be considered.Through this paper provide some useful experiment data on combustion of sewage sludge and coal and mixture between them for combustion technology.
