中文摘要：
在沉降炉上进行生物质与煤的混烧试验，分析研究生物质与煤混烧对可吸入颗粒物（PM10）的粒径分布、排放特性及其形貌的影响。试验结果表明：4种燃料混烧的PM10＋排放仍为相似的双峰分布；混烧时燃烧过程明显分为脱挥发分和焦炭燃烧2个阶段：LPSA煤与锯末混烧时排放的PM10浓度最低，并且当氧气含量增加时，PM10（粒径最大不超过1．mm的颗粒物）变化幅度较小，而PM10＋（粒径位于1.0-10μm之间的颗粒物）则有较大程度的增长；对于同一种煤与生物质混烧时，PM10的形貌有相似之处。在0．1μm处LPSA煤与生物质混烧形成的细微颗粒物大多呈柱状，而PDSB煤与生物质则大多呈碎片块状：并且在4．3μm处除了各自原有的柱状或碎片状结构外，还出现了部分光滑圆球体颗粒结构。
英文摘要：
Co-combustion of coal with biomass was carried out in a laboratory-scaled drop tube furnace to investigate the effect of co-combustion of biomass with coal on the inhaled particulate matters（PMi0） emissions, distribution and its morphology. The results showed that the PMI0 from the co-combustion of biomass with coal still had a similar bimodal distribution; the co-combustion process had two combustion stages including devolatilization and char combustion. In addition, the emission of PMi0 from the co-combustion of sawdust and LPSA coal was the least; and with the increasing of oxygen ratio, the PM1.0（particle size below 1.0μm） varied little, while PM1.0. （particle size between 1.0-10μm） increased significantly. For one coal co-combusted with biomass, the morphology of PM10 had some similarities. At Dp（the diameter of particle）--0.1μm, the morphology of particle from co- combustion of LPSA/biomass blends was mostly columnar and that from co-combustion PDSB/biomass blends was mainly massive; At Dp--4.3μm, both of them presented partly slick spherical particulate matters.
