Abstract

Abstract

The demand for the harmless treatment of combustible solid waste (CSW) is increasing, and the incineration method can effectively realize the resource utilization, reduction and harmlessness of CSW. The thermochemical properties of CSW are of great significance in the organization of the combustion process. Due to the diversity of sources and types of CSW, the characterization of the thermochemical properties of CSW, especially CSW mixture is an urgent problem. If some typical CSW is used as "pseudo-components", the thermochemical characteristics of other CSW can be simplified, efficiently and systematically characterized. In this study, the principal component analysis (PCA) method was used to reduce the dimension, and then the CSW was classified with the selection of the pseudo-components based on the criteria of completeness, independence and certainty, as well as the central criteria and the simple criteria. Finally, eight species including latex gloves, hard plastic bags, PE, PET, starch, lignin, cellulose and hemicellulose were selected as pseudo-components. And the above several pseudo-components had been characterized by thermogravimetric analysis, based on this, a method for characterizing the heat conversion unit of CSW was established. Fitting industrial CSW, which gray relation grade was as high as 0.989, the practicability and accuracy of the method of dimension reduction and clustering were verified. This study established a method for characterizing the thermal conversion of CSW, which could provide a reference for the thermal conversion and disposal of CSW.
