Description

Anlage zur Verfeuerung von Abfallbrennstoffen, wie Holz, Lohe u. dgl., die in einer Mühle aufbereitet sind, und Verfahren zur Benutzung der Anlage Die Erfindung betrifft eine Anlage zur Verfeuerung von Abfallbrennstoffen, wie Holz, Lohe u. dgl., die in einer Mühle aufbereitet sind, und besteht darin, daß diese Brennstoffe einer mit einem anderen Brennstoff (Hauptbrennstoff) beschickten, mit dem Brennraum verbundenen Mühlenfeuerung zugeführt werden.Plant for the combustion of waste fuels, such as wood, fire, etc., which are processed in a mill, and method of using the system Die Invention relates to a plant for burning waste fuels, such as wood, Lohe and the like, which are processed in a mill, and consists in the fact that this Fuels one charged with another fuel (main fuel) with the combustion chamber connected to the mill furnace.

Zwei verschiedenartige feste Brennstoffe werden zur Verfeuerung als Brennstaub gewöhnlich gesondert aufbereitet und verfeuert. Bei Verwendung von Mühlenfeuerungen wäre diese ,gesonderte Verfeuerung unwirtschaftlich und kaum durchführbar. Die A@ufbereitiing eines Brennstoffgemisches ist jedoch nur möglich, wenn die M.ahlbarkeit beider Brennstoffe ungefähr gleich ist. Wegen dieser Mängel sind Mischbrennstoffe meist auf Rosten, häufig auch der Abfallbrennstoff in einer Staubzusatzfeuerung verfeuert worden. Letztere befriedigen jedoch selten wegen der verschiedenartigen Betriebsbedingungen der beiden Feuerungsarten.Two different types of solid fuels are considered to be burned Fuel dust usually processed and burned separately. When using mill firing this separate combustion would be uneconomical and hardly feasible. The preparation a fuel mixture is only possible if both fuels are available is roughly the same. Because of these defects, mixed fuels are mostly on rust, often the waste fuel has also been burned in an additional dust furnace. The latter, however, are seldom satisfactory because of the different operating conditions of the two types of combustion.

Da jedoch Holz in ganz anderer Stückgröße anfällt als Kohle und auch andere Feuchtigkeit und Mahlbarkeit hat als diese, wird erfindungsgemäß das Holz erst in einer Reißmühle vorzerkleinert, bevor es in der Mühlenfeuerung gemeinsam mit der Kohle fertiggemahlen wird.However, since wood is produced in a completely different piece size than coal and also has different moisture and grindability than these, the wood is according to the invention first pre-crushed in a shredder before it is joint in the mill furnace is finished grinding with the coal.

Die Zeichnung gibt eine Darstellung der Anordnung gemäß der Erfindung.The drawing gives an illustration of the arrangement according to the invention.

Die der Brennkammer i vorgeschaltete Mühlenfeuerung 2 ist in ihrer Anordnung und Wirkungsweise bekannt. Ihr fließt die Rohkohle aus einem Bunker 3 durch eine Zuteilvorrichtung 4, einen Mischbunker 5 'und einen weiteren Zuteiler 6 zu. Die pneumatisch durch Rohrleitung 7 herangebrachten Holzspäne werden in einem Bunker B gesammelt, in einer Vormühle 9 vorzerkleinert und vorgetrocknet und dann mit dem anderen Brennstoff gemeinsam in die Mühlenfeuerung aufgegeben.The mill furnace 2 upstream of the combustion chamber i is in its Arrangement and mode of operation known. The raw coal flows out of a bunker 3 by an allocation device 4, a mixing bunker 5 'and a further allocator 6 to. The pneumatically brought through pipe 7 wood chips are in one Bunker B collected, pre-crushed and pre-dried in a pre-mill 9 and then abandoned together with the other fuel in the mill furnace.

Zu diesem Zweck saugt der Mühlenventilator io mittels regelbarer Leitungen i i und 12 Feuergase aus dem Brennraum und Kaltluft ,an und fördert sie mit dem zerkleinerten Brennstoff durch Rohrleitung 13 in .einen Zwischenbunker 14. Die Abluft entweicht durch Rohrleitung 15 ins Freie; sie kann jedoch ,auch, wie am Bunker 8 durch Rohrleitung 16 gezeigt, weiterverwendet werden. Aus dem Bunker 14 werden mittels Zuteiler 17 die Späne in den Mischbunker aufgegeben. Es können natürlich auch beide Brennstoffe getrennt voneinander der gemeinsauren Mühlenfeuerung 2 aufgegeben werden. Auch kann in bekannter Weise der Ventilator saug- oder dizickseitig so angeordnet werde daß er nur von Reinluft durchströmt wi, Die Einschaltung eines Zwischenbunkers.' ist nicht erforderlich, jedoch wünschenswert, da erfahrungsgemäß der Anfall des Zusatzbrennstoffes in der Fabrikation selten genügend gleichmäßig ist.For this purpose the mill fan io sucks by means of adjustable lines i i and 12 fire gases from the combustion chamber and cold air, and promotes them with the Crushed fuel through pipe 13 in .ein intermediate bunker 14. The exhaust air escapes through pipe 15 to the outside; However, it can also, as in bunker 8 shown by pipe 16, can be further used. From the bunker 14 are means Distributor 17 placed the chips in the mixing bunker. Of course, both can Fuels separated from each other of the common auric Mill firing 2 are abandoned. In a known manner, the fan can also be used on the suction or thick side will be arranged in such a way that only clean air flows through it Intermediate bunker. ' is not necessary, but desirable, as experience has shown the accumulation of the additional fuel in production is seldom sufficiently uniform is.

Durch die beschriebene Arbeitsweise wird der Zusatzbrennstoff so weit vorbereitet, daß er bei Aufgabe in die Mühle bezüglich seiner Mahlbärkeit ungefähr der des Hauptbrennstoffes nahekommt. Es ist somit eine Leistungsminderung oder gar ein Verstopfen der Mühle 2 ausgeschlossen. Die Mühle 2 wird zweckmäßig als Schlägermühle zur Zerkörnung, die Vormühle 9 dagegen als Reißmühle mit messerartigen Schlägern ausgebildet. Beim Anfeuern kann mit Vorteil der im Zwischenbunker 1q. lagernde vorgetrocknete Brennstoff allein verwendet werden.The additional fuel becomes so far as a result of the method of operation described prepared that he should be fed into the mill with regard to his grindness that of the main fuel comes close. It is thus a reduction in performance or even clogging of the mill 2 is ruled out. The mill 2 is useful as a beater mill for granulation, the pre-mill 9, on the other hand, as a shredding mill with knife-like beaters educated. When firing up, the 1q. stored pre-dried Fuel can be used alone.
