  • Coal-blended fuel, method for combusting the same, and coal fuel for use in coal-blended fuel
    Patent number: 9353324
    Abstract: This mixed coal fuel is obtained by mixing a low-grade coal and residual coal. The residual coal is obtained by separating, through evaporation, a solvent from concentrated solids left over when a solution portion, which contains soluble coal components in solvent, is separated from a slurry obtained by mixing and heating coal and a solvent. Furthermore, the ratio (base/acid) of basic components to acidic components contained in ash of the residual coal is lower than that of the low-grade coal.
    Type: Grant
