| Abstract: | This study addressed the mechanism of coal blend combustion for fine particulates reduction,and the impact of blend ratio and combustion atmosphere on the reduction properties. Coal blends from a lignite and a bituminous coal,with different blend ratios(9:1,7:3,5:5,3:7,1:9) and different combustion atmosphere(O_2/N_2 and O_2/CO_2 atmosphere.),were combusted in a drop tube furnace to analyze the concentration and element composition of the particulate matter generated, which collected by a low pressure impac... |
