Description

Process for the production of artificial charcoal from peat. Subject of Invention is a method for producing charcoal from peat.

The peat taken from the moor is mixed thoroughly and put in centrifuges crushed to a very fine mass with the addition of water added under pressure. Most suitable are centrifugal machines with screen jackets according to patent 3367-17 made of flat wire lamellas with outwardly conical channels are. With the extremely fine sieves present in these devices channels running conically on the outside and also through the during operation Adding water under pressure for other reasons is absolutely safe Effect of the spin achieved. The crushing of the raw peat mass is through significantly supports the masses of water set in motion, as it does it is also already known that you can grow with a powerful jet of water alone Ripping loose peat masses and crushing them. Because of this strange dispersion a product is obtained which has a flour-like handle.

Then the mass is extensively and intensively slurried in a known manner, to reduce the ash content in the incineration of the end product achieve: The mass prepared in this way is now thrown against the filter under strong pressure, in order to effect an intimate pressing of the mass in addition to the excretion of the water. A filter according to patent 366365, which consists of strips consists, (lie strung on bars, have different strength and alternate are provided with internal and external teeth. The application of this filter at the present method gives a sure guarantee by its design reliable continuous operation. The design of said filter allows manufacturing even the finest passage channels, so that the solid components stick to it of the sludge masses on the surface of the filter fully achieved, the water on the Extremes are removed and the solid components are strongly compressed. The single ones Peat particles are pressed tightly onto and into one another, so the resulting peat leaves Mass contains almost no air. This is the high specific weight and the extraordinary strength of the end product. An operation occurs in Phenomenon which, according to B e r g i n s, can be referred to as the coalification process.

The resulting mass is then divided into molds and ready to dry designed. The piece now shrinks, namely in all dimensions almost simultaneously. However, the surface shrinks much faster than the core and thereby exerts a special pressure on the latter. It shows Now a peculiar process develops in which the coalification process is further promoted will, which takes place here in a particularly pronounced form, since the individual peat particles are in the finest distribution and on (read Can merge tightest. The result is an artificial charcoal, the coal-like one Possesses character.

The production of this charcoal takes place in standing plants and is therefore feasible throughout the year.

The advantages of the process product are: r. high specific Weight, so extraordinary tightness and therefore small volume, 2. great hardness; <The product does not crumble, burns completely without its solid form lose and without any slag formation, and has only a very low ash content, 3. (las briquette is dust-free and does not get dirty, .1. Increasing the usefulness without Addition of other fuels.

Claims (1)

PATENT CLAIM: Process for the production of artificial charcoal from peat, characterized in that (1a13 the raw peat mass with the addition of water by means of centrifugal machines with jackets according to Patent 3367.17 is comminuted to a flour-like handle, slurried and filtered under pressure through a filter according to Patent 366365, whereupon the cup is allowed to dry out.
