在水泥回转窑烧成系统中,烧成带温度是影响水泥熟料质量的关键因素,但是在实际生产过程中回转窑烧成带温度不能直接测量,因此利用LS_SVM(最小二乘支持向量机)方法建立通过窑头罩温度、窑主机电流、烟室温度、分解炉出口温度、篦速逼近烧成带温度的虚拟测量模型;其后基于水泥生产线DCS可采集的相关检测变量,建立不同工况下窑头喷煤量与软测量出的烧成带温度之间的动态模型。
In the cement rotary kiln firing system, the sintering zone temperature is the key factor affecting the quality of cement clinker, but in the actual production process, the rotary kiln firing zone temperature can not be directly measured. Therefore, LS_SVM (least squares support vector machine) Methods A virtual measurement model was established based on temperature of kiln hood, current of kiln, temperature of smoke chamber, outlet temperature of calciner and speed of grate approaching sintering zone temperature. Based on the relevant detection variables collected by DCS in cement production line, different working conditions The dynamic model between the kiln head coal injection volume and the soft measured temperature of the sintering zone.
