 alle Luft, die für die Verbrennung erforderlich ist, vom Anfang an beigemischt würde, würde die Temperatur im   Ranale 10 80   weit herabgesetzt, dass die erste Vergasung erschwert wäre. 



  Da die Luftzufuhr in das Rohr   J   durch Druck oder Zug von dem Bodenrohr 9 aus erfolgt, trägt sie auch dazu bei, den pulverförmigen Brennstoff schwebend zu erhalten, bis die vollständige Verbrennung stattgefunden hat. Ist eine sehr ausgedehnte Flamme erwünscht, so kann man diese Luftmenge auch an mehreren Punkten, weiter in den eigentlichen Feuerraum hinein, zuführen. Durch den   beschriebenen Ofen erhält   man eine vollständige Entzündung und Verbrennung bei genau abgemessener Luftmenge. 



   Der Feuerraum 6 hat noch eine weitere praktische Bedeutung. Wenn die Brennstoffzufuhr bei irgend einer Gelegenheit freiwillig oder unverschuldet ohne Abstellung des Luftstromes unterbrochen werden sollte, würde der Entflammungsraum ohne einen solchen Feuerraum abgekühlt werden, wodurch eine neue Entzündung erschwert und der Dampfkessel unnötigerweise durch den kalten Luftstrom angestrengt werden würde. In der beschriebenen Weise wird eine solche Abkühlung verhindert und die Brennstoffzufuhr kann nach Belieben vermehrt, vermindert oder ganz unterbrochen werden, um zu jeder Zeit wieder zu "vollem Feuer" überzugehen, ohne dass das geringste Hindernis bei der Entzündung entsteht. 



   PATENT-ANSPRÜCHE : 
1. Beweglicher   Entzündungsofen   für   pulverförmigen   Brennstoff, dadurch gekennzeichnet, dass oberhalb des Rostes ein mit schraubenförmig gestalteten Schirmen ausgestatteter vorne offener, nach unten aber geschlossener Mischraum (4) vorgeschen ist und in dessen Verlängerung ein hinter dem Rost gelegener, die Fortsetzung des Feuerraumes   (6)   bildender röhrenförmiger   Entflammungsraum     (5),   in welchen von unten schräg nach oben und nach hinten gerichtete Luftzuführungsrohre münden, angeordnet ist.

 If all the air required for the combustion were to be added from the start, the temperature in the Ranale 10 80 would be lowered so that the first gasification would be difficult.



  Since air is supplied into the pipe J by pushing or pulling from the bottom pipe 9, it also helps to keep the powdered fuel floating until complete combustion has taken place. If a very extensive flame is desired, this amount of air can also be fed into the actual furnace at several points. The oven described provides complete ignition and combustion with a precisely measured amount of air.



   The combustion chamber 6 has a further practical meaning. If the fuel supply were to be interrupted on any occasion, voluntarily or through no fault of one's own, without shutting off the air flow, the ignition chamber would be cooled without such a furnace, which would make a new ignition more difficult and the steam boiler would be unnecessarily strained by the cold air flow. In the manner described, such a cooling is prevented and the fuel supply can be increased, decreased or completely interrupted at will in order to go back to "full fire" at any time without the slightest obstacle to the ignition.



   PATENT CLAIMS:
1. Movable ignition furnace for powdery fuel, characterized in that above the grate a mixing chamber (4) which is open at the front and which is closed at the bottom and which is equipped with helical screens is provided and in its extension a continuation of the combustion chamber (6 ) forming tubular inflammation chamber (5), in which from below obliquely upward and rearward directed air supply pipes open, is arranged.
