Description
Verfahren zum Trocknen oder Schwelen von Brennstoffen durch gleichzeitige Innen- und Außenheizung. Beim Schwelen von Brennstoffen ist es bekannt, das Gut innen und' außen zugleich zu beheizen. Dabei hat die Innenheizung den Zweck, Wärme auf das Gut zu übertragen. Nach der Erfindung dient die Außenheizung lediglich dazu, Strahlungsverluste der Innenheizung zu verhüten. Hierzu wird die Außenheizung auf einer Temperatur gehalten, die gleich oder angenähert gleich ist dem Wärmegrade der Innenheizung, so daß diese allein den das Trocknen oder Schwelen bewirkenden Heizstrom bildet. Dieses Verfahren gestattet auch, kostspielige Heizmittel, wie überhitzten Wasserdampf, wirtschaftlich anzuwenden.Process for drying or smoldering fuels by simultaneous Indoor and outdoor heating. In the smoldering of fuels, it is known to be the property to be heated inside and outside at the same time. The purpose of the interior heating is to provide warmth to transfer to the estate. According to the invention, the external heating only serves to To prevent radiation losses from the interior heating. For this purpose, the outside heating is switched on held at a temperature that is equal to or approximately equal to the degree of warmth the internal heating, so that these alone cause the drying or smoldering Forms heating current. This method also allows expensive heating means such as superheated steam, economical to use.
Das Verfahren kann in folgender Weise ausgeübt werden.The procedure can be carried out in the following ways.
Wenn z. B. überhitzter Wasserdampf, der im Gegenstrom zu dem Brennstoffe eine Drehtrommel durchströmt, mit q.50° in diese eintritt und sie mit i5o° verläßt, dann wird in einen die Trommel umschließenden Heizraum an dem gleichen Ende, wo der überhitzte Dampf eintritt, Heizgas von etwa 45o° eingeführt, das am anderen Ende mit entsprechend tieferer Temperatur austritt. Demzufolge werden die Wände der Trommel nirgends heißer als deren Inneres. Das ist besonders wertvoll für die Stelle der höchsten Temperatur, weil hier ein durch die äußere Beheizüng der Trommel in diese hineingetragener Wärmeüberschuß die Schwelerzeugnisse zersetzen könnte.If z. B. superheated steam flowing in countercurrent to the fuel flows through a rotary drum, enters it at q.50 ° and leaves it at i5o °, then into a boiler room enclosing the drum at the same end where the superheated steam enters, heating gas of about 45o ° introduced, the one at the other At the end with a correspondingly lower temperature. As a result, the walls will nowhere hotter than the inside of the drum. This is especially valuable to them Place the highest temperature, because this is due to the external heating of the drum Excess heat carried into this could decompose the smoldering products.
Zum äußeren Beheizen der Trommel dienen vorteilhaft Abgase.Exhaust gases are advantageously used for external heating of the drum.
