主　　题：municipal solid waste(MSW) low emission gasification and melting dioxins heavy-metal 

摘      要：In order to eliminate secondary pollution caused by municipal solid waste(MSW)incineration,a MSW gasification and melting process is *** process is expected to reduce the emission of pollutants,especially heavy-metals and *** this paper,the combustible components of MSW and simulated MSW were gasified in a lab-scale fluidized bed at 400°C-700°C when the excess air ratio(ER)was between 0.2 and *** experimental results indicated that the MSW could be gasified effectively in a fluidized bed at approximately 600°C-700°C when excess air ratio was *** melting characteristics of two typical fly ash samples from MSW incinerators were *** results indicated that fly ash of pure MSW incineration could be melted at approximately 1,300°C and that of MSW and coal co-combustion could be melted at approximately 1,400°*** temperature was over 1,100°C,more than 99.9%of the dioxins could be decomposed and most of the heavy-metals could be solidified in the *** on the above experiments,two feasible MSW gasification and mel-ting processes were proposed for low calorific value MSW:(1)sieved MSW gasification and melting system,which was based on an idea of multi-recycle;(2)gasification and melting scheme of MSW adding coal as assistant fuel.
