Particulate matter from coal combustion is one of the most main atmospheric pollutants in urban China currently. It has caused serious damage to the environment and human health. A 3012H type automatic smoke-dust(flue-gas) monitor was used to collect PMs in front of the ESP of 1^# boiler in Shajiao C power plant in Humen. The influence of boiler load and coal type on the emission characteristics of the fly ash was studied. The particle size distribution, chemical composition, mineral constituent and morphology characteristics of the fly ash were also analyzed. The results indicate that the fractions of PM₁ and PM_2.5 increase with the rising of boiler load, however, the concentration of the total smoke-dust decreases. The level of PM₁ and PM_2.5 becomes higher when the blending ratio of Yitai coal increases. The coal is easy to form coal cells containing molten spherules when burned in a high load boiler, and to form porous cenospheres when burned in a low load boiler. The mineral component of the ashes collected from different situations is similar.
