ABSTRACT:
For the purpose of briquetting organic solid materials, such as brown coal or bituminous coal, the materials are heated by hot water and/or steam and under super-atmospheric pressure to temperatures exceeding 160.degree. C. After discharging the organic solid materials, which have become dried to a great extent, the generated steam is separated by sucking off the steam without substantially cooling effect, bitumen-forming substances present within the organic solid materials thereby rapidly becoming homogeneously distributed. These homogeneously distributed binding agents give the compressed briquettes obtained a high strength and good mechanical properties when using substantially reduced compacting pressures as compared with known briquetting processes.
