主　　题：Solid refuse fuel small-scale combustor thermogravimetric analysis waste gas concentration 

摘      要：In the production(as co-fuel or alone)of solid refuse fuel(SRF),knowledge about the characteristics of the raw materials is required for an ecofriendly and effective combustion *** are commonly produced by drying combustible waste and removing incombustible matter,resulting in a higher combustibility as compared to the original ***,the characteristics of SRFs may highly vary depending on where and from which materials they were ***,we investigated the characteristics of various SRFs using thermogravimetric analysis(TGA).As a TGA sample is commonly small,on the scale of milligrams,and,unlike homogeneous fuels,SRFs are heterogeneous,individual SRF samples analysed with this method may not represent the bulk material,and sample properties may vary significantly between ***,we further performed combustion experiments using a small-scale combustor and sample sizes from 1 to 10 *** optimise SRF combustor design and determine the SRF characteristics,proximate,elemental,heating value,TG,and differential thermogravimetric analyses were conducted,and weight losses and gas concentrations at different temperatures were measured upon *** lower heating values of the three analysed SRFs were 20,976,16,873,and 19,762 kJ/kg,and their Cl contents were 0.89,0.95,and 1.27 wt.%(legal criterion[Cl]2.0 wt.%).TGA and small combustor experiments showed that complete weight loss was achieved below 500°***,CO was detected until 620°C.
