Abstract:

Against the identification issue of the correlation model between coke oven flue temperature and regenerator top temperature, a model identification method based on least square method with pre-estima?鄄tion of confidence interval was put forward. This method can effectively eliminate the effect of gas reversal on different trends of flue temperature and regenerator top temperature. By using pre-calculation of confi?鄄dence band, the issues of the correct fitting data brought by compact identification data and incorrect physics meaning can be avoided.
