Description
Patented Sept. 4, 1951 AGGLOMERATES OF FUEL AND MANUFACTURE PROCESS Antoine Vloeberghs, Antwerp, Belgium No Drawing. Application October 1, 1946, Serial N 0. 700,389. In Belgium September 22, 1939 6 Claims.
In my patent application Serial No. 700,391, now abandoned, there has been disclosed the means to manufacture fuel agglomerates by applying two distinct cements, of which one respectively is capable to give to the mass a good resistance during the whole duration of the combustion and the other is capable of giving to the mass a sufficient water-proofness, so that it may be kept in the open air which is necessary for a normal and prolonged stocking.
According to the present improvements, one substitutes for the sulfate liquor commended in the principal patent, a certain quantity of a polymerizable product, so that the latter brings about a cement capable of giving to the mass its water-proofness. Preferably, a synthetic resin will vbe used as polymerizable product, for instance a condensation product of phenol and formaldehyde.
From the tests made by the inventor, it results that the agglomerates of finely divided anthracite to which are added less than 6% of waste sulphite liquor from the manufacture of the cellulose and less than 3% of synthetic resin, resist perfectly to all operations to which coal is generally submitted and resists even a prolonged immersion in boiling water.
The synthetic resin and the sulphite liquor can be introduced either separately, or as a compound previously formed by the mixture of the two cements. Thereafter, the solid fuel as finely divided, mixed with its binder and submitted to an appropriate mechanical action, in order to be briquetted in the shape of agglomerates of pre-determined sizes. In order to assure a quicker hardening of the agglomerates, these will preferably go through a drying-oven in which will be maintained a temperature equal or slightl superior to 100 C.
What I claim is:
1. A fuel agglomerate comprising coal dust, a suitable amount of waste sulphite liquor up to less than 6%, and a suitable amount of a phenolformaldehyde resin up to less than 3%.
2. A fuel agglomerate comprising finely divided anthracite, a suitable amount of waste sulphite liquor up to less than 6%, and a suitable amount 2 of a phenol-formaldehyde resin up to less than 3%.
3. In a process for manufacturing coal briquettes, the steps of adding to coal dust a, suitable amount, up to less than 6%, of waste sulphite liquor for binding the particles of said coal dust and a suitable amount, up to less than 3% of a phenol-formaldehyde resin for waterproofing the resultant mixture, moulding said mixture and drying the same by heat.
4. In a process for manufacturing coal briquettes and the like, the steps of adding to finely divided anthracite a suitable amount, up to less than 6%, of waste sulphite liquor for binding the particles of said anthracite, and a suitable amount, up to less than 3%, of a phenolformaldehyde resin for waterproofing the resultant mixture, moulding said mixture and subjecting the same to heat.
5. In a process for manufacturing coal briquettes and the like, the steps of adding to coal dust a suitable amount, up to less than 6%, of waste sulphite liquor for binding the particles of said coal dust, and a suitable amount, up to less than 3%, of a phenol-formaldehyde resin for waterproofing the resultant mixture, moulding said mixture and subjecting said moulded mixture to a temperature of about C.
6. In a process for manufacturing coal briquettes, the steps of adding to coal dust the following previously prepared mixture: a suitable amount, up to less than 6% of waste sulphite liquor and a suitable amount, up to less than 3% of phenol-formaldehyde resin; moulding the resultant agglomerate and subjecting the same to a temperature of about 100 C. in an oven.
