Emission properties of fine particulate matter, namely PM_<2.5> for the particle size smaller than 2.5μm, were studied during co-firing experiments of two coals. Co-firing tests were conducted at 1200℃ and 1450℃ in a lab-scale drop tube furnace. The effect of Ca-based compounds on the formation of PM_<1+> (ranging from 1μm to 2.5μm) and PM_1, (≦1μm) has been investigated. At 1450℃, higher content of Ca results in lower emission of PM_<1+>, but for PM_1, the trend is reverse. While at 1200℃, no relationship has been observed between PM_<1+>, PM_1, and the content of Ca in mixing coal samples.
