788,068. Agglomerating fuel.. MINISTER OF POWER. Jan. 30, 1956 [Jan. 28, 1955], No. 2601/55. Class 50. In a process of making lump fuel from medium and weakly caking coal particles of the coal are fed from a hopper 1 on to an endless belt conveyer 2 to pass between two electrodes 4 where they are heated by dielectric heating until the plastic properties of the coal are uniformly developed throughout the particles, the plastic particles are then agglomerated in passing over a corrugated screen 5 vibrated transversely. The plates 4 are adjustably mounted and as shown are inclined towards one another and connected to a high-frequency energy source of between 5-10 megacycles per second, giving a heating rate of 15-30 C. per minute. The coal particles may be preheated to 300 C. prior to subjecting them to dielectric heating.; The agglomerating of the coal particles may be effected in a rotating drum or on a rotating plate. The agglomerated particles may be carbonized, e.g. on a travelling band carbonizer.
