高炉中喷吹废塑料的可行性研究(Ⅰ):——废塑料与煤粉的燃烧特性对比研究 总被引:10,自引:0,他引:10
为了研究向高炉中喷吹废塑料的可行性,对几种常见废塑料与高炉喷吹用煤粉的燃烧特性进行了对比研究。结果表明:废塑料具有良好的燃烧性能;废塑料的开始燃烧温度和激烈燃烧温度都比煤粉低,燃烧时间较煤粉短,燃烧速度快,燃烧灰尽少,因此更有利于高炉喷吹。 相似文献

高炉中喷吹废塑料的可行性研究(Ⅱ)——废塑料与煤粉的热特性对比研究 总被引:1,自引:0,他引:1
为了研究向高炉中喷吹废塑料的可行性,对几种常见废塑料与高炉喷吹用煤粉在升温过程的热行为进行了对比研究。结果表明:与煤相比,废塑料热值高,从着火到燃烧结束所需时间短,且占整个升温过程耗时比例低。从而表明从热特性角度分析,废塑料适用于高炉喷吹。 相似文献

运用系统分析的方法,对不同比例混合以及不同粒径大小的废塑料和煤粉混合物在高炉喷吹条件下的燃烧性能进行了对比研究。探明了混合物在炉腔内燃烧时的脱挥发分析出情况以及燃烧率的影响因素。分析结果表明,混合物中废塑料的添加比例和粒径的大小均是影响混合物燃烧性能的主要因素,从喷吹单一煤粉到喷吹废塑料与煤粉的比例达到5:5时,混合物的燃烧率从3.5%提高到35.5%。混合物的粒径大小从135~150μm变为30~50μm时,燃烧速率快了将近15%。 相似文献
