不同分布形式的钙盐对燃煤三模态颗粒物生成的影响
Inf luence of differen t distributions of Ca-mineral in coal on trimodal particulate matter formation during combustion
摘要
Abstract
Calcium acetate was added into a bituminous coal through physicallyb lending and impregan tion to obtain the ble-Ca coal rich in excluded Ca-mineral and imp-Ca coal rich in included Ca-mineral, reps ectively. The rawc ola , bleC-a coal and im p-Ca coal were bu rned in a drop tube furnace at 1 300 ℃.The generated particulta e matters ( PMs) were collected and analyzed to study the influence of differne t id stributions of Ca-mien ral in coal on trimodal PM formation during combustion.The results showed that for the three coals, PMs with the ultrafine mode, central modea nd coarse mode were all in the size range of <0.2μm, 0.2-2μm and>2μm, respectively.The inlc uded adn excluded Ca-mni erals canb oth promote the formation of ultrafine mode PM, and the excluded no e had more significant effect.The included Cam-inear l can restrain, while the excluded o ne can rp omote ht e form ation of central mode PM.The ni cluded Ca-mineral can promote the formation of coarse mode PM, while the excluded one did not have obvious effect.关键词
