PROCESS FOR MAN UFACTU'RING BRIQUETTES.
Application filed November 29, 1924, Serial No. 752,976, and in Belgium December 3, 1923.
The invention relates to a process for the manufacture of combustible briquettes from carboniferous' substances, such as bituminous coal or the like.
It has for its object more especially to enable combustible briquettes to be made of bituminous coal having the characteristics of anthracite.
, The process may be best understood when 1" described in relation to apparatus by means of which it is carried out, and reference is therefore made to the sole figure of the drawing which shows, partly in plan and partly in section one form of apparatus which 1 applicant has found practical for the manufacture of briquettes according to his novel process. s
In the drawing a represents an open-mold press into which the bituminous coal is fed after having been suitably comminuted. The chamber of this press has the shape and size of a briquette, into which chamber the comminuted soft coal is fed and compressed by means of a piston, the briquettes thus formed being forced into the tube a. This tube has the same internal diameter as the briquettes, the latter fitting tightly the bore of the tube as they are progressively forced along by successive impulses of the piston.
Circular metallicplates, not shown, are fed into the press between each charge of carbonaceous material, said plates being substantially of the same diameter as the internal diameter of the tube a and functioning as separators, preventing the adherence of the briquettes one to another. The forward part of the tube 0 is heated by suitable means such as the furnace e, the latter, in the illustrative embodiment of the apparatus, in-
40 eluding an oven or retort f which surrounds the tube a. The column of briquettes within the tube is under considerable pressure in all directions, said pressure being transmitted by the piston of the press and being resisted by the cylindrical walls of the tube and by the briquettes in the discharge end.
of the tube. The object of heating the briquettes while under pressure is to render viscous or liquid the hydrocarbons or coal tars therein contained, to cause these to permeate the intramolecular interstices of the briquette, transforming, in a few minutes, the bituminous coal into a coal having anthracitic qualities. At this stage in the process the metallic separators perform the important function of heat conductors so that the briquettes are uniformly heated thrlqughout to the temperature of the tube wa s.
That part of the tube d which lies beyond the furnace has a cooling function, and in this part of the tube the metallic separators serve uniformly to dissipate the heat from the briquettes, thereby inducing a gradual contraction and avoiding the cracking of the briquettes which would follow their unequal cooling. It is important that the briquettes be cooled within the tube 0 and while under pressure, so that certain of the hydrocarbons which might be volatile at atmospheric pressure may be condensed by the cooling of the briquette before the pressure is released.
It has been found desirable in some instances to vent the tubec as by the pipe 0 to ermit the escape of some of the gases which are volatile throughout the entire process. v
In the drawing an auxiliary press I) has been introduced, which applicant has found convenient in applying the requisite pressure to the briquettes in the tube 0. This auxiliary press may, however, be considered as a laboratory expedient, amounting merelyto a duplication of the press a and being entirely unessential to the carrying out of the process.
What I claim and desire to protect by Letters Patent is:
1. The process for making brlquettes of anthracitic quality from bituminous coal/ 90 which consists in forming briquettes, foreing them successively into and through a tube in a column which tightly fits the bore of said tube, heating the briquettes in a forward part of the tube while under pressure to arsufficient temperature to cause fluorescence of the hydrocarbons therein contained cooling the briquettes while still under pressure in the tube.
2. The process for making briquettes of 100 'anthracitic quality from bltuminous coal which consists in forming briquettes, ar-
ran 'n conductive se arators in alternation wit t e briquettes, orcing the briquettes successively into and through a tube in a column which tightly fits the bore of said 5 tube heating the briquettes in the forward part of the tube while under pressure, to a suflicient temperature to cause fluorescence still under pressure in the rearward part of 10 said tube.
In testimony whereof I afiizr my signature.
