Problems solved by technology

[0004] However, in the current cement enterprises, the control of the amount of coal fed to the kiln head mainly depends on the knowledge and experience of the operating engineers, and due to the differences in the technical level of the operating engineers and the operation behavior is easily dominated by subjective wishes, the firing quality of cement clinker is affected.

Abstract

The invention discloses a rotary cement kiln head coal feeding control method. The method comprises the following steps: on the basis of actual production data of a cement factory, an initial kiln head coal feeding amount set is obtained through case-based reasoning; and on the basis of the deviation between a firing zone temperature real-time value and a firing zone temperature expected value anda firing zone temperature change rate, the trend change of the current firing working condition is judged according to expert rules, and the kiln head coal feeding amount is corrected and compensatedfor. A design method of the control method for modifying the given rotary cement kiln head coal feeding amount based on case-based reasoning in combination with expert rules is established, and the difference of knowledge and experience among different operation engineers is eliminated.

Description

technical field [0001] The invention relates to a coal feeding control method for a cement rotary kiln kiln head, belonging to the technical field of cement production control. Background technique [0002] The cement industry is one of the pillar industries of my country's national economy, and the cement rotary kiln has become the main equipment for calcining cement clinker in modern cement production. It has become an important development direction of the cement industry to build intelligent cement production plants and improve the high degree of automation, integration and greening of cement enterprises. [0003] Clinker is an intermediate product in cement production, and its quality directly determines the final quality of cement. The calcination process of cement clinker in the rotary kiln is the key link to determine the quality of cement clinker. [0004] However, in the current cement enterprises, the control of the amount of coal fed to the kiln head mainly dep...
