Development Organization, Japan Abstract The mercury release behavior in bituminous coals, and the partitioning rate of mercury in solids and gaseous in flue gases have measured to develop technologies for evaluating the partitioning of mercury in coal combustion process and develop in-situ adsorption and removal technologies using three kinds of experiment equipments - a thermo-balance, a drop-tube furnace (DTP), a bench- scale pulverized coal combustion furnace. The results showed that about 20 to 60% of the mercury in coal was released between 573 K and 673 K, which was the range of temperature in which the release of th
