| With the rapid development of economy, improvements of people's life, as well as aggravation of urbanization process, the treatment of Municipal Solid Waste (MSW) has attracted great attention of the whole society. Nowadays, gasification and melting technology has been considered the most potential replacement technology of the incineration in the 21st century for its typical advantages, such as thoroughly harmlessness, significant reduction, widely material adaptability and efficient energy and material recovery efficiency. Therefore, it is very important and necessary to research and develop gasification and melting technique based on the situation of China.A medium scale fluidized-bed gasifier was used to study the gasification characteristics of typical polymer (PE and rubber) and typical biomass (paper and bamboo) components of MSW. Temperature influence on characteristics of gasification products was analyzed, such as the components of the syngas and non-gaseous product, heat value and yield of syngas, mass and energy distribution of each product, as well as combustion and melting characteristics of fly ash.Gasification characteristics of artificial MSW were studied in the fluidized-bed gasifier. Results show that raising of the temperature benefits the gasification reaction. With the temperature increasing, heat value and yield of syngas, mass fraction and energy transformation efficiency of gasification products increase, but the content of tar decreased. Gasification reaction is sufficient at 750℃, mass fraction and energy transformation efficiency of gasification product are 93.25% and 85.69% respectively. In addition, ash melting point is lower than melting temperature that fly ash can be melted in melting furnace entirety.Dioxin content of artificial MSW on gasification was studied. It is shown that the inhibit function on formation of dioxin will be stronger with the excess air ratio decreasing.
