No.35 Effect of Magnesium Additives on PM2.5 Reduction during Pulverized Coal Combustion

抄録

The effect of different Mg-containing additives on the reduction of particulate matter with an aerodynamic diameter smaller than 2.5 μm(PM_<2.5>)during pulverized coal combusted was investigated. Experimental results indicate that, the Mg-containing additives tested here imposed a pronounced impact on the particle size distribution of PM_<2.5>. However, the shape as well as surface properties of particles generated by different additives considerably differed from each other, which confirmed that different additives are associated with the inherent coal minerals in different forms, thereby experiencing different evolutionary processes during combustion.
