Description
In. vielen Fällen, insbesondere bei Darrfeuerungen, fällt einem langgestreckten Rauchgaskanal die Aufgabe zu, in parallel laufenden Luftkanälen -die Luft zu erwärmen, die dann beispielsweise zum Darren verwendet wird.In. In many cases, especially in the case of Darrfeuerungen, falls an elongated The task of the flue gas duct is to heat the air in parallel air ducts, which is then used, for example, for kilning.
Bisher bestehen die Wandungen der Rauchgaskanäle aus Schamottegestein, das in der Höhe d-es Kanals ,geschichtet ist. Es hat sich jedoch gezeigt, daß auf diesem Wege der Wärmeaustausch zwischen den Rauchgasen und der parallel oder im Gegenstrom in den Luftkanälen strömenden Luft verhältnismäßig .klein ist, mit der Folge, daß derartig,-Anl@a.gen verhältnismäßig groß sind.So far, the walls of the flue gas ducts consisted of firebrick, which is layered at the level of the canal. However, it has been shown that on this way of heat exchange between the flue gases and the parallel or im Countercurrent in the air ducts flowing air is relatively .klein, with the Consequence that such, -Anl @ a.gen are relatively large.
Dem trägt die Erfindung dadurch Rechnung, daß die Seiten .des Rauchgaskanals durch vom Kanalboden bis zur Kanaldecke ununterbrochene, gegenüber dem Boden schräg gestellte Platten aus feuerfestem Stoff gebildet sind.The invention takes this into account by the fact that the sides of the flue gas duct through uninterrupted from the canal floor to the canal ceiling, at an angle to the floor Asked panels are made of refractory material.
Es hat sich gezeigt, daß, vom Feuerungsraum abgesehen, derartige Platten aus Scharnottematerial den gestellten Anforderungen bezüglich .der Feuerfestigkeit vollauf genügen und daß bei Anwendung dieser Platten, wenn diese vom Boden bis zur Kanaldecke ununterbrochen sind, eine Schrägstellung möglich ist. Diese Schrägstellung hat eine vergrößerte Oberfläche der Trennwandung gegenüber dem parallel laufenden Luftkanal zur Folge und somit in Verbindung mit der geringeren Wandstärke einen erheblich vergrößerten Wärmeaustausch.It has been shown that, apart from the furnace, such plates made of bulkhead material that meets the requirements regarding fire resistance fully suffice and that when using these plates, if these from the ground to the Duct ceiling are uninterrupted, an inclination is possible. This inclination has a larger surface area of the partition wall compared to the parallel one Air duct result and thus in connection with the smaller wall thickness one significantly increased heat exchange.
Die Zeichnung zeigt schematisch einen einzigen Strang eines Rauch,gaskanals mit parallel laufendem Luftkanal im Querschnitt. Die Seitenwände i und 2 des Rauchgaskanals 3 sind durch Schamotteplatten gebildet, die vom Boden q. bis zur Kanaldecke 5 ununterbrochen sind, so daß sie, wie gezeichnet, ohne weiteres gegenüber dem Boden d, oder der Decke 5 schräg gestellt sein können. Außerhalb der Seitenwände i und 2 liegen die beiden Luftkanäle 6 und 7, die über den Raum 8 über -der Decke 5 miteinander in Verbindung stehen. In diesen Luftkanälen 6, 7 und 8 strömt Luft, diie z. B. zum Darren verwendet wird. Diese strömende Luft wird über den Wandungen i und 2 und. über der Decke 5 erwärmt. Da die Seitenwände i und 2 aus in Höhenrichtung ununterbrochenen Platten bestehen, so ist eine Schrägstellung, wie gezeichnet, möglich, mit der Folge, da,B die geheizte Oberfläche der Kanäle 6 und 7 vergrößert ist. Abgesehen hiervon wird aber der Wärmeaustausch auch dadurch erhöht, daß die Platten i und 2 eine geringere Wandstärke besitzen als eine Steinmauer, die unter Verwendung von übereinandergeschichteten Formsteinen errichtet wunde.The drawing shows schematically a single strand of a smoke, gas duct with parallel air duct in cross section. The side walls i and 2 of the flue gas duct 3 are formed by fireclay panels, which from the floor q. up to the sewer ceiling 5 uninterrupted are so that they, as shown, readily opposite the bottom d, or the Ceiling 5 can be inclined. Outside the side walls i and 2 are the two air ducts 6 and 7, which are connected to each other via the space 8 via the ceiling 5 Connected. In these air ducts 6, 7 and 8 air flows, which z. B. to Darren is used. This flowing air is over the walls i and 2 and. heated over the ceiling 5. Since the side walls i and 2 are uninterrupted in the vertical direction Plates exist, so an inclination, as shown, is possible, with the result, since, B the heated surface of the channels 6 and 7 is increased. Apart from that but the heat exchange is also increased by the fact that the plates i and 2 are less Wall thickness possessed as a stone wall made using layered Form stones built sore.
Wie aus der Zeichnung ersichtlich, besteht auch die Decke 5 des Kanals 3 aus Platten.As can be seen from the drawing, there is also the ceiling 5 of the channel 3 made of plates.
