A refuse derived fuel (RDF) molding machine and a Thermogravimetric Analyzer were used to investigate parameters in RDF molding processes and thermal characters of RDF products, respectively. In the process of preparing RDF using bio-drying products, the appropriate parameters of moisture content, particle size and molding pressure were 30%, <1mm and 2MPa, respectively. The range of falling strength of RDF was 95~100% under such condition, which meant high efficiency of molding without any volumetric expansion. The heat value of RDF was relative higher when particle size is 1~2mm than that of others. Thermal characteristics of RDF with the particle size of <1mm were remarkably different from those with the particle size of 1~3mm. The fitting of TG curve was great using first order kinetics equation. The results indicated a great potential of preparing RDF using municipal solid waste after bio-drying.
