As a means of co-processing of waste,cement kiln co-processing system has the advantages of wide application range,large processing capacity and environmental protection,etc.Under a background of green development,more and more cement plants have built waste co-processing system.When the co-processing system is running in a cement line in Hebei province,the clinker output of the system is 3 800t/d,the standard coal consumption is 103kg/t.cl.Meanwhile,there are problems of high resistance and high outlet temperature of preheater system.In order to achieve the purpose of energy conservation and reducing consumption,our company has modified the burning system on the base of combining with the actual production situation of the production line.After reform,standard coal consumption has reduced about 5kg/t.cl,clinker production has increased about 600t/d,preheater system pressure has reduced about 1 000Pa.On the basis of significant energy conservation and reducing consumption,a significant increase in production has been achieved,which is in advanced level in domestic co-processing production line.
