Description

Die Erfindung betrifft eine Lufteinführting für besonders große Feuerräume, insbesondere für Kohlenstaubfeuerung. Es ist schon vorgeschlagen worden, die Luft durch Luftzuführungsrohre, die auf der Außenseite durch nebeneinanderliegende, vom Kühlmittel durchflossene Rohre umgeben sind, in das Innere des Feuerraumes einzuleiten. Hierdurch wird ein besserer und schnellerer Ausbrand der Gase erzielt.The invention relates to an air inlet for particularly large fireplaces, especially for pulverized coal combustion. It has already been proposed to air by air supply pipes, which are connected on the outside by side by side, from Pipes through which coolant flows are to be introduced into the interior of the combustion chamber. This results in a better and faster burnout of the gases.

Erfindungsgemäß wird vorgeschlagen, das Luftzuführungsrohr an einer unteren Kante einer im Feuerraum liegenden Strahlungstafel anzuordnen.According to the invention it is proposed that the air supply pipe on a to arrange the lower edge of a radiation panel lying in the furnace.

Hierdurch wird nicht nur die Einführung von Luft in das Innere des Feuerraumes erreicht, sondern es wird auch bewirkt, daß der Aufprall der Feuergase auf die Strahlungstafel verringert und dadurch die Verschmutzung der Strahlungstafel weitgehend verhindert wird. Außerdem ist es auch möglich, auf diese Weise auf eine einfache und betriebssichere Weise das Luftzuführungsrohr zu haltern.This not only prevents the introduction of air into the interior of the The combustion chamber is reached, but it also causes the impingement of the fire gases on the radiation panel and thereby the pollution of the radiation panel is largely prevented. It is also possible to do this in a simple and reliable way to hold the air supply pipe.

Die Abb. i und 2 zeigen ein Ausführungsbeispiel. Die Abb. i gibt einen Querschnitt durch einen kohlenstaubgefeuerten Kessel wieder, bei dem in den unteren Kanten der Schottheizfläche 7 das Luftzuführungsrohr 3 eingesetzt ist. Die Kühlrohre können entweder nach Abb. ?a, die einen Schnitt durch die Schottheizfläche zeigt, parallel zum Luftzuführungsrohr 3 oder nach Abb. 2b senkrecht um das Luftzuführungsrohr 3 herumgeführt werden.Figs. I and 2 show an embodiment. Fig. I shows a cross section through a pulverized coal-fired boiler in which the air supply pipe 3 is inserted in the lower edges of the bulkhead heating surface 7. The cooling tubes can either Fig.? A, which shows a section through the bulkhead, parallel to the air feed tube 3 or in fig. Be guided around the air supply tube 3 orthogonal 2b.

Die Luftaustrittsöffnungen befinden sich an der unteren Kante der, Schottheizfläche und werden durch Auseinanderbiegen der Kühlrohre 6 gebildet. In gleicher Weise ist es auch möglich, das Luftzuführungsrohr von oben innerhalb der Schottheizfläche herabzuführen.The air outlet openings are located on the lower edge of the bulkhead heating surface and are formed by bending the cooling tubes 6 apart. In the same way, it is also possible to lead the air supply pipe down from above within the bulkhead heating surface.
