-
摘要: 运用SPSS统计软件, 分析研究了木屑气化碳黑后形成的衍生燃料的商业化条件.根据商业化性能要求(抗压强度、挥发成分及热值) 与制备条件(粘接剂、成型温度及成型压力) 的相关性, 以确定最优制备条件.由衍生燃料燃烧温度、燃烧值、燃烧时间、灰分、含水率、总硫分及燃烧现象与传统商用木炭燃烧性质的对比, 确定最优应用条件.最后, 通过市场现状分析, 表明该衍生燃料具备价格和环保效益等多方面竞争优势.研究结果说明, 在综合考虑技术可行与经济效益后, 该衍生燃料的最优制备条件是: PVA-1000粘接剂添加量5%, 成型温度150℃, 成型压力130 kg/cm2, 制备出的产品符合目前商业化产品规范.其最优应用条件是: 最高温度可达550℃, 平均燃烧温度约350℃, 热值约24.284 MJ, 燃烧时间87 min/kg.整个燃烧过程温度释放均匀, 无烟无臭无味, 总硫分仅0.19%.燃烧后氮氧化物与硫氧化物的排放量比市售传统木炭低, 粒状污染物也在排放标准内, 燃烧后维持原型, 易清除, 最优市场价格为6元/kg.该项技术具有良好的环保及经济效益, 预计将有广泛的市场应用前景.Abstract: 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.
