摘要
基于趋势分析方法，研究了焦炉加热燃烧过程工况辨识方法。通过分析焦炉加热燃烧过程工艺，建立了包括单个炭化室工况辨识和焦炉加热燃烧过程工况辨识的信息融合总体结构。基于趋势分析方法分析安装在焦炉上升管的热电偶数据的一致性和可靠性，提取特征点，采用专家规则对各个炭化室的数据进行分析，辨识单个炭化室的工况；对单个炭化室的输出空间进行整理、分类，作为焦炉加热燃烧过程工况识别的输入空间，采用模糊信息融合的方法进行信息融合，得出焦炉加热燃烧过程的实时工况。仿真分析验证了所提方法的有效性。
Based on trend analysis, an operating-state identification method for combustion process of coke ovens was studied. The mechanism of coking process was analyzed and the information fusion structure was presented, which consisted of identification of coking chamber operating-state and identification of combustion process operating-state. The trend analysis method was adopted to judge if the temperature acquired from thermocouples installed in the rising pipe could be used to judge the operative-state of coking chambers, and then, feature points were extracted, and the expert rules were used to identify the operative-state in single coking chambers. And finally, the out- puts of single coking chambers were arranged and classified as inputs of operating-state identification of combustion process. And the information was fused with the fuzzy method to get the operative-state of the combustion process of a coke oven. The simulation results prove the effectiveness of the proposed method.
