Description
WILLIAM FREDERICK COLLINS, OF LONDON, ENGLAND.
MANUFACTURE OF FUEL-BRIQUETS.
No Drawing.
To all whom it may concern:
Be it known that I, WILLIAM FREDERICK COLLINS, associate of the Royal College of Science, a subject of the King of Great Britain, residing at 26 Overton road, Stockwell, London, England, have invented new and useful Improvements in the Manufacture of Fuel-Briquets; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in the manufacture of briquets, and has for its object to provide for binding the fuel material without the necessity for employing as a binding agent substances which materially reduce the calorific power of the briquets when burning.
According to this invention I mix pulverized coal or other suitable carbonaceous material with powdered solid sodium silicate or water glass; the proportion of Water glass usually required is from 3 to 6% of the mass. This I find gives improved results as compared with the process described in specification of former Letters Patent granted to me No. 15958 /O2. I may add to the mixture if desired a metallic oxid, such, for instance, as oxid of iron, in the proportion of say one half of one per cent. of the mass, or I may use a calcium compound or other similar material which will assist in binding and hardening the mass.
The mixture is rendered thoroughly plastic by heat and moisture, the best results being hitherto obtained by passing the mixture through a steam jacketed pug-mill into the interior of which steam is also introduced. The mixture is finally molded and compressed under suitable pressure to the required form whilestill in a heated condition.
The blocks when taken from the molds are ready for use without the necessity of subjecting them to a further process for drying and hardening.
Specification of Letters Patent.
Application filed July 27, 1908.
Patented June 7, 1910.
Serial No. 445,568.
In cases where the briquets are liable to be subjected to the action of moisture I can, if desired, envelop them in a jacket of waterresisting material such as pitch, tar or the like. I wish it to be understood, however, that this envelop is not added for calorific or binding purposes but merely to assist the briquets in withstanding the action of the air or moisture which in course of time more or less affects the briquets.
I am aware that heretofore it has been proposed to use alkali-silicates both liquid and solid for strengthening binding materials used in the manufacture of fuel briquets, but I am not aware that before the date of my invention a pulverized solid alkali silicate has been employed alone as a binding material.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be per formed, I declare that what I claim is 2- 1. The herein described process for the manufacture of fuel briquets, which consists in combining pulverized carbonaceous ma terial and powdered solid sodium silicate both being in a dry condition, thoroughly mixing the ingredients in a dry condition, subjecting the incorporated dry mixture to the action of heat and moisture, and subsequently forming the mass into briquetsr 2. The herein described process for the manufacture of fuel briquets, which consists in combining pulverized carbonaceous material, powdered solid sodium silicate, and a small proportion of a metallic oxid, the materials being in a dry condition, thoroughly vmixing the ingredients in a dry condition,
then subjecting the incorporated dry material to the combined action of heat and moisture and then forming the mass into briquets.
WILLIAM FREDERICK COLLINS.
