Verfahren zur Herstellung von Holzbriketts und von in Brikettform gepressten Unterzündern.
Gegenstand der vorliegenden Erfindung bildet ein verfähren zur Herstellung von Holzbriketts und von in Brikettform gepressten Unterzündern aus Forstabfällen und Pech, welches dadurch gekennzeichnet ist. dass diese Abfälle, wie z. B. Reiser. Nadeln und Fruchtzapfen, in zerkleinertem Zustande mit einem Gemenge von geruchlosem Hartpech, Natronsalpeter und Paraffin innig verrührt, hierauf in Formen gebracht und schliesslich bei gleichzeitiger Erwärmung gepresst werden.
Die so erhaltenen Briketts haben holzähnliches Ausgehen und die Festigkeit einer mittelharten Holzgattung, jedoch eine wesentlich längere Brenndauer und Heizkraft als diese.
Infolge ihrer grossen Dichte nehmen sie bedeutend kleineres Volumen ein als die an Heizkraft gleichwertige Hoizmenge ; sie sind fast unhygroskopisch, besitzen geringen Aschengehalt und sehr niedrige Entzündungstemperatur.
Zur Abgrenzung des Schutzumianges soll bemerkt werden, dass durch da, D. R. P. or. 74889 und das Österr. Patent Nr. 70024 schon Verfahren bekannt geworden sind, nach welchen derartige Heizkörper unter Verwendung von Forstabfällen mit Hilfe heissflüssigen Harzes hergestellt worden sind. Von diesen bekannten Verfahren unterscheidet sich das vorliegende dadurch, dass dem Hartpech auch Paraffin und Salpeter, also auch Stoffe beigemengt werden. welche nicht als Bindemittel geltend gemacht werden können.

Process for the production of wooden briquettes and of underfighter pressed in briquette form.
The subject matter of the present invention is a process for the production of wood briquettes and of lower igniters pressed in briquette form from forest waste and pitch, which is characterized. that this waste, such as B. Reiser. Needles and fruit cones, in the crushed state, are intimately mixed with a mixture of odorless hard pitch, sodium nitrate and paraffin, then shaped and finally pressed with simultaneous heating.
The briquettes obtained in this way have a wood-like appearance and the strength of a medium-hard type of wood, but a much longer burning time and heating power than this.
As a result of their great density, they occupy a considerably smaller volume than the amount of wood equivalent in heating power; they are almost unshygroscopic, have a low ash content and a very low ignition temperature.
To delimit the protective envelopes, it should be noted that da, D. R. P. or. 74889 and the Österr. In patent no. 70024 processes have already become known, according to which such radiators have been produced using hot-liquid resin using forest waste. The present one differs from these known processes in that paraffin and saltpeter, i.e. also substances, are added to the hard pitch. which cannot be used as binding agents.
