Patent GB-790024-A (GB)
Title: Process for the hot-briquetting of coal
IPC: C10L5/08
Filed: 1955-11-15
Abstract: Powdered coal and similar fuel material is formed into briquettes without the use of a binder by a process in which the material is preheated to just below its softening point and compressed at a temperature which is raised rapidly from the softening point to the temperature of optimum mouldability, the material fusing into briquettes.  Temperature control is achieved by adjusting the softening point and/or the character of the compression operation. To lower the softening temperature the material may be preheated in drying drums, first in a co-current of oxygen-containing gas and then in a counter-current of steam. Factors which control the character of the compression operation are the amount of material in the mould cavity and the speed of compression; also, in the extrusion type of briquetting press, the length of the extrusion channel.  The press may be heated externally.  Existing briquetting presses may be used, including roller press and ring-roller presses, the compression adjustment being effected by the amount of the charge.  The material may be cooled in the press before the release of pressure to allow gas formation to cease.  Suitable materials besides coal and coal mixtures are mixtures of coal and coke or coal and semi-coke. Typical preheating temperatures are 350 DEG -380 DEG C., range of temperature rise during compression 20 DEG -80 DEG C., corresponding to a final pressure of about 5-7 tons/sq. in.  Numerical examples are given for gas coals and non-bituminous coal.
