In order to investigate and reduce the formation of fine particles generated during the combustion process of fuels mixed with a high percentage of woody biomass fuels, a drop tube furnace was used in this study. Two types of coal were prepared by adding 5, 15 or 30% of two types of woody biomass, and the formation behavior of fine particles (PM0.1, PM0.5, PM2.5, and PM10) was investigated. The results showed that, depending on the combination of coal fuel and biomass fuel, the addition of biomass fuel did not increase the emission of PM0.5 and PM10 in some cases compared to the case where only coal was burned. This result is an interesting finding that the addition of biomass can reduce the amount of fine fly ash generated and reduce the heat transfer inhibitors such as slag and fouling in the boiler.
