Status and Outlook of Data Mining Technology in Coal fired Boiler and Waste Incineration Boiler

Based on the advantages and disadvantages of data mining algorithms that applied in coal fired boiler optimization operation and pollutant emission control,including association rules,cluster analysis,neural networks as well as support vector machines,this paper reviews the status on fault diagnosis,boiler combustion optimization,pollutant emission reduction and unit optimization operation by data mining technology. The analysis shows that artificial neural network is relatively widely used due to its strong robustness and self learning ability. In the future,based on the incineration mechanism and coupled with other algorithms,it can be further applied in engineering. Furthermore,on basis of existing application of data mining technology,the future development and application of the intelligent waste incineration boiler that has largely optimization space under high control requirements have been prospected. We suggest to combine the data mining technology with the cloud computing platform,consider the actual working conditions and characteristics of the waste incineration process,and further develop data preprocessing methods to expand the dynamic data sampling range and improve the actual operation efficiency and generalization ability of the model.
