An oxyfuel combustion model of refuse derived fuel(RDF)was established by the Aspen Plus software.The effect of combustion temperature and excessive oxygen coefficientδon product of the RDF oxyfuel combustion was studied.The results showed that:the atmosphere had little influence on SOx and CO2 generation;the NOx generation increased with the combustion temperature T and excessive oxygen coefficientδ;with an increase in combustion temperature T

the SO2 generation increased while that of the SO3 decreased

they showed an opposite trend as the excessive oxygen coefficientδrising;the CO generation increased sharply when the combustion temperature T was higher than 1 200℃but dropped significantly when the excessive oxygen coefficient was larger than 1.0.
