Abstract

The invention discloses an evaluation and correction method and device for thermal efficiency online calculation parameters of a rotary cement kiln. The method comprises the following steps that a quality threshold value of a deviation thermal efficiency parameter in the frequent operation process of the rotary cement kiln is calculated; the real-time thermal efficiency parameter standard deviation of the rotary cement kiln is calculated by using a thermal efficiency model; the real-time thermal efficiency parameter calculation standard deviation and the quality threshold value of the deviation thermal efficiency parameter are compared, and parameter data for carrying out thermal efficiency calculation of the rotary cement kiln are determined; and the in-kiln secondary inlet air quantity is corrected and calculated. According to the method and device, the problem that part of parameters are mismatched along with continuous production when the thermal efficiency model participates in field actual calculation is successfully solved, the calculation accuracy of the thermal efficiency model is ensured, and the thermal efficiency online calculation accuracy in the cement clinker sintering process is improved.
