Description
Kohlenpressling für Heizzwecke. Die Erfindung betrifft einen Kohlenpress- ling für Heizzwecke, welcher am besten. die Form der üblichen Kohlenbrikette aufweist, aber auch eine andere Form haben kann. Die ser Kohlenpressling besteht gemäss der Er findung aus einem gepressten und getrock reten Gemisch von in überwiegender Menge verwendetem Kohlenstaub und von Lehm als Binde- und Füllmittel.
Am vorteilhafte sten verwendet man etwa doppelt so viel Kohlenstaub als Lehm; indessen kann man auch etwas weniger Kohlenstaub und etwas mehr Lehm benutzen, wenn nur der Kohlen staub den Lehm an vorhandener Menge etwas überwiegt.
Zur Herstellung eines solchen Presslings \werden zum Beispiel 10 Pfund Kohlenstaub mit 4-5 Pfund fettem Lehm und etwas Was ser zu einer knetfähigen Masse durch und durch vermengt,, worauf diese in einer Form gepresst und das Formstück getrocknet wird.
Der erhaltene Pressling brennt ausge zeichnet und bleibt beim Brand schön zusam- inenigebacht. Die Hitzeentwicklung ist eine Hervorragende. Der als Bindemittel dienende Lehm trägt in der Gluthitze zum Zusammen halten der Hitze wesentlich bei und bewirkt ein langsames Abbrennen des Presslings, so dass derselbe verhältnismässig lange anhält. Die Aschenbildung ist im Vergleich zu den gewöhnlichen Kohlenbriketts unwesentlich höher.
Dagegen sind angesichts der Verwen dung des überall erhältlichen Lehms die Her stellungslzosten des vorliegenden Presslings bedeutend geringer, so da.ss von diesem Stand punkt aus der vorliegende Kohlenpressling bei der Vorzüglichkeit seines Abbrandes als äusserst ökonomisch zu gelten hat.
Der vorliegende Kohlenpressling eignet sich sowohl für den Hausbrand, als auch für die Industrie.
Zur Erhöhung der Beständigkeit beim Liegen kann der Kohlenpressling aussen mit einer dünnen Leimschicht überzogen werden,' etwa dadurch, dass man ihn in eine wässerige Leimlösung eintaucht.
Pressed coal for heating purposes. The invention relates to a pressed coal for heating purposes, which is best. has the shape of the usual coal briquette, but can also have another shape. According to the invention, this pressed coal consists of a pressed and dried mixture of predominantly used coal dust and clay as a binder and filler.
It is most advantageous to use about twice as much coal dust as clay; however, one can use a little less coal dust and a little more clay, if only the coal dust somewhat outweighs the clay in the amount available.
To produce such a pellet, for example, 10 pounds of coal dust are mixed through and through with 4-5 pounds of fatty clay and some water to form a kneadable mass, whereupon this is pressed in a mold and the shaped piece is dried.
The pellet obtained burns excellently and stays nicely together during the fire. The heat development is excellent. The clay, which is used as a binding agent, makes a significant contribution to keeping the heat together in the scorching heat and causes the pellet to burn off slowly so that it lasts for a relatively long time. The ash build-up is insignificantly higher than that of normal coal briquettes.
On the other hand, in view of the use of clay, which is available everywhere, the production costs of the present pellet are significantly lower, so that from this point of view the present coal pellet has to be regarded as extremely economical in view of the excellent burnup.
The present pressed coal is suitable for both domestic and industrial use.
To increase the resistance when lying down, the carbon compact can be coated on the outside with a thin layer of glue, for example by dipping it in an aqueous glue solution.
