摘　　要：对不同配比复合垃圾衍生燃料做实验试烧,并对燃烧产生的NOx、SO2等燃烧排放污染物进行了监测.利用扫描电镜(SEM)和能谱(EDX)结合联用技术观察了生物质垃圾与煤混合压制燃料的燃烧颗粒的微观形态特征.结果表明,随着生物质比例的加大,发现飞灰颗粒有细化的现象.Cl元素的排放主要出现在燃烧初期.钾的主要存在形式是氯化钾.飞灰颗粒的所有能谱分析中并没有检测到重金属元素的存在.Combustion characteristics and RDF pollutants emission of the railway solid waste mixture with coal have been studied. Pollutants mechanism as well as the corresponding control has also been investigated. The microstrueture characteristic and the major elements analysis of the fly ash from cocombustion of biomass with coal was conducted by using scanning electron microscope （SEM） and X- ray energy dispersive microanalysis （EDX）. The results show that the shape of fly ash particles is various. Most particles are irregular. The phenomenon of the particle adsorption existed among different grain sizes. Potassium was detected in EDX analysis of all fly ash particle. Experimental resuh showed that the primarily existent form of potassium is potassium chloride in co-combustion of biomass with coal, and the heavy metals were not detected in EDX analysis of all the fly ash particles.
