Abstract: Influence factors of TG-DTG method to test the combustion characteristic of refuse derived fuel (RDF) for the cement kiln was studied; the relationship between the proximate analysis and the combustion characteristic parameters of RDF was discussed. The combustion characteristic parameters were taken as a combustion process evaluation for both RDF and coal, and their influence on thermal parameters of the cement kiln system was discussed. The research results showed that for RDF combustion characteristic TG-DTG test, the heating rate should be 20℃/min, surroundings gas oxygen concentration should be 21%, the flow rate should be 100ml/min. When ash content of the refuse derived fuel reduced, the volatile content increased, the ignition temperature would decrease, relatively the burning time extended. RDF combustion characteristic had an important influence on cement kiln operation stability, therefore cement production should cope with its sufficient combustion characteristic research, strictly control the proportion of alternative fuels, at the same time, pay close attention to the thermal parameters of kiln system.
