Outline of Final Research Achievements

Low-rank coals are widely distributed across the world. High content of alkali and alkaline earth metals in low-rank coals cause serious ash related problems such as ash deposition, fouling and ultrafine particulate matter emission (e.g. PM2.5) during air and Oxy-Fuel combustion of coal. This study aims to clarify the effects of a bituminous coal blending on coarsening of fine particulate matter and the addition of kaolin (clay mineral) of optimal particle size on reduction of amount of fine particulate matter during coal combustion.
