Abstract (en)

[origin: WO9610093A1] The transportability of dry pulverized coal originating from raw coal having an average HGI of 30 or above can be improved by adhering an organic compound which has a polar group and is substantially water-soluble to the pulverized coal, examples of such an organic compound including anionic surfactants, cationic surfactants, amphoteric surfactants, organic acids and salts thereof, and phenol compounds and salts thereof. The transportability of the pulverized coal is improved to enable the use of the coal as the fuel to be injected into a metallurgical furnace or combustion furnace. Further, the use of the compound prevents the occurance of hanging and channeling in a hopper and the choking of a pipeline.
