Abstract
Provided is a manufacturing method for a briquetted solid fuel that can reduce the briquetting cost while maintaining the strength of the briquetted product. A mixed oil that includes a heavy oil and a solvent oil, and a porous coal are mixed to obtain a slurry. The slurry is dewatered by heating to obtain a dewatered slurry. Solvent oil is separated from the dewatered slurry to obtain a cake, the cake is heated, and solvent oil is further separated from the cake to obtain a modified coal. Moisture is added to the modified coal to obtain a moist modified coal with a moisture content of 3 wt % to 10 wt %, and then the moist modified coal is briquetted under pressure.
