Description
Wie bekannt- ist, macht das Verbrennen backender Kohle auf Wanderrosten große. Schwierigkeiten, weil durch Krustenbildung der Durchtritt der Verbrennungsluft (Unterwind) gehindert wird. Die zur Behebung dieser Schwierigkeit nötige Ver-_ ringerung der Rostgeschwindigkeit und Einregulierung des Unterwindes verursachen eine Minderung der Kesselleistung und des Wirkungsgrades.As is known, burning charcoal makes on traveling grates size. Difficulties due to the crust formation of the combustion air (Under wind) is prevented. The reduction necessary to resolve this difficulty the speed of the grate and the adjustment of the under wind cause a reduction the boiler output and the efficiency.
Es sind nun Vorrichtungen bekannt, bei denen die backende Schicht dadurch aufgerissen Wird, da.ß feststehende wassergekühlte Rohre von oben in die Schicht eingreifen. Es ist auch schon eine Vorrichtung bekanntgeworden, bei der ein im Feuerraum über der Brennstoffschicht angeordneter, drehbar gelagerter, gekröpfter, stabartiger Rohrkörper verwendet wird, der bei der Drehung in .die Brennstoffschicht eintaucht. Dabei wird dieser Körper in so schnelle Drehbewegung versetzt, daß er nicht nur die. Brenustogschicht zusaxnmendTückt bzw. zerteilt, sondern die Kohle gleichzeitig auch noch in Wanderrichtung des Rostes fördert. In allen diesen bekannten Fällen findet also eine Relativbewegung ,des Schürkörpers gegenüber der wandernden Brennstoffschicht statt. Dabei entsteht erheblicher Kraftaufwand und starker Verschleiß. Gemäß der Erfindung findet ebenfalls ein gekröpftes, gekühltes Rohr, das über der Brennstoffschicht im Feuerraum angeordnet ist und. von oben in regelmäßigen Zeitabständen in, die Brennstoffschicht eintaucht, Verwendung. Das Rohr führt jedoch eine Schwingbewegung aus, bei der es in etwa .senkrechter Richtung von oben in die eing@edrüekt und kurze Zeit danach aus der Schicht -wieder nach oben herausgezogen wird: Beim Eintauchen drückt --es auf die Brennistoffschicht und zerstört deren Kruste. Eine Relativbewegung zwischen der wandernden Schicht und dein eingetauchten Rohr findet bei der kurzen Tauchzeit im praktischen Umfang nicht ,statt. Daher .ist auch der Verschleiß der Vorrichtung nach der Erfindung gegenüber den bekannten erheblich geringer.Devices are now known in which the baking layer Is torn open because fixed water-cooled pipes from above into the Intervene shift. A device has also become known in which a rotatably mounted, cranked, which is arranged in the combustion chamber above the fuel layer, rod-like tubular body is used, which when rotating in .the fuel layer immersed. This body is set in such rapid rotation that it not only the. Brenustogschicht compresses or divides, but the coal at the same time also promotes in the direction of movement of the grate. In all of these known In cases there is a relative movement of the stoker in relation to the wandering one Fuel layer instead. This creates a considerable amount of force and wear and tear. According to the invention there is also a cranked, cooled tube that is above the Fuel layer is arranged in the furnace and. from above at regular intervals in, the fuel layer is immersed, use. However, the pipe performs an oscillating movement in which there is an approximately vertical direction from above into the indented and short Time afterwards it is pulled out of the layer again upwards: When immersing presses it on the fuel layer and destroys its crust. A relative movement between the migratory layer and your submerged pipe takes place at the short one Dive time on a practical scale does not take place. Hence the wear and tear of the Device according to the invention compared to the known is considerably lower.
In. der Zeichnung ist ein Ausführungsbeispiel dargestellt. Das im Feuerraum i gekröpfte, drehbar gelagerte Rohr z wird durch den Antrieb 3 in eine durch den Pfeil q. angedeutete Schwingbewegung versetzt und drückt in kurzen Abständen auf die vom Rost bewegte Kohleschicht 5, deren Kruste dadurch aufgebrochen wird.In. the drawing shows an embodiment. The im Firebox i cranked, rotatably mounted pipe z is converted into a by the drive 3 by the arrow q. indicated swinging movement displaces and pushes at short intervals on the carbon layer 5 moved by the grate, the crust of which is thereby broken open.
