Optimal Conditions for Manufacture of Refuse Derived Fuel(RDF) from Carbon Black of Wood Chips by SPSS Statistic Analysis Software

This paper aims at analyzing by SPSS software the manufacture and commercialization conditions of RDF from carbon black of wood chips.The optimal manufacture conditions were determined by correlation analyses between the commercial application requirements (compression strength, volatile content & heat value) and control parameters (additive, press temperature & press stress).And, the optimal application conditions were determined by combustion temperature, released heat, combustion duration, ash content, moisture content, total sulfur content & combustion phenomena in addition to the basic property comparison between commercial charcoal & the RDF.Finally, the analysis of the market indicated the competitive advantages of RDF in both price and environmental benefit.By taking the technical feasibilities and economic evaluation into account, the optimal manufacture conditions of the RDF are: 5% PVA-1000 additive, 150 ℃ press temperature, 130 kg/cm² press stress for fitting the specifications of the present commercial charcoal.The optimal application conditions are: 550 ℃ reach combustion temperature, 350 ℃ average combustion temperature, heating value 24.284 MJ and 87 min/kg combustion duration.Different from the commercial charcoal, the RDF is characterized by uniform heat release, clean smell and low NOx and SOx emission during the combustion.In addition, particle emission also accords with the emission regulations of Taiwan and its shape remains unchanged after combustion.The competitive marketing price is estimated to be 6 Nt$/㎏.With great environmental and economic benefit, the RDF is bound to be popular in the market.
