Patented in the German Empire on February 15, 1891.

According to the previous method of preparation of briquettes treated with coal army the coals with tar and water mixed well with each other by means of mechanical aids, the mixture drained, pressed into briquettes, which the latter then with artificial heat was used to remove the water that was still in it and any volatile tar products.

By this process of mixing the tar with coals and water and Subsequent drying of the briquettes requires mechanical equipment and a lot of space Drying ovens are required, and it is the purpose of the present invention mechanical devices for mixing the tar with the coal waste, as well as special ones Eliminate drying ovens.

The new procedure essentially consists of the following:

Coal breeze, coke, lignite or the like Materials are in a moistened state in a suitable vapor-tight, a higher Vapor pressure resistant container is brought and placed on the surface of the coals and so on, such a quantity of tar poured as in proportion to the quantity of coal is necessary to make good briquettes. The vessel is then closed and done a tube attached in the lid of the same from a steam boiler of steam flow left, that from the upper layer of coal through the whole mass of the coal waste penetrates and through an opening made in the lower part of the container, which with a valve or tap is provided, can escape.

The effect of this action of steam is that the tar is heated by the steam, which Tar products driven into the coal and the latter coated or mixed with tar and at the same time a large part of the water is expelled and at the same time with it the steam escapes through the opening in the bottom, as well as earthy parts which are in the Coal are included to be discharged with.

The draining water contains various usable tar products that are collected and can be aborted.

In practice it turns out that in this way all volatile tar products are obtained and can be used while a mixture of coals is in the container and tar residue remains, both substances are well mixed with one another and relatively good anhydrous.

The time during which the steam acts on the coal and tar mixture, depends partly on the vapor pressure and partly on the quantity and consistency of the materials used, but in any case enough time must be given in order to permit an abundant passing over of tar products.

This hot and relatively dry mixture is then withdrawn from the container and either immediately put into the briquette press or, if the circumstances allow it allow · unchecked consumed as fuel.

Which flow off through the bottom opening of the container at the same time as the steam and water Tar products are collected and separated from one another in a known manner.

Instead of the tar on the surface of the Pouring charcoal mass can also be used before placing it in the container mixed with the coal in a suitable proportion, which is particularly advantageous is when one has to deal with thick, heavy tar.

Claims (2)

Patent Claims: 1. To produce fuel from Coal or coke breeze, lignite or similar material in connection with coal tar, Oil residues and similar substances the moistening of the coal parts with water and the action of steam on the mixture of coal produced in this way, Tar and water. 2. In the case of the under i. marked procedure for the production of fuel from a mixture of coal or coke breeze, water and tar of the products of tar by means of high-tension water vapor, which is driven through the coals and tar mix will.
