The main object of this paper is to verify the greenhouse gas reduction effects obtained by using biosolid fuel as an alternative fuel in coal-use plants. The various physical properties of the biosolid fuel produced from four kinds of solid-fuelizing systems were analyzed, and its properties were examined. The biosolid fuel was then mixed with coal, and the burning test was carried out in a laboratory-scale combustion furnace and the actual power plant. The flammability and exhaust gases were investigated, and the influences of using biosolid fuel at power plant were checked. The greenhouse gas reduction effect due to the usage of biosolid fuel was verified by making a trial calculation. As a result, it was confirmed that greenhouse gases can be greatly reduced compared with the incineration system. It was also verified that the amount of the greenhouse gases reduction can exceed the discharge.
