Description

Es sind Rekuperatoren bekannt, bei. welchen in die Luftkanäle Speicherkörper eingefügt sind, so daß die Rekuperatoren gleichzeitig als Wärmespeicher wirken, ohne daß eine Verschlechterung der Wärmeübertragung zwischen Abgasstrom und Luftstrom besteht. Derartige Rekuperatoren sind beispielsweise von Bedeutung für die Beheizung von Flammöfen, weil sich bei'diesen nach jeder Charge ίο eine wesentliche Erniedrigung der Abgastemperatur ergibt, so daß an sich auch die Vorwärmung der Luft bzw. des-. Gases, vermindert wird, während gerade in idieser Periode die Vorwärmung von besonderer. Bedeutung ist. Die Speicherwirkung" der Rekuperatoren wirkt hier ausgleichend. Die. "Erfindung betrifft eine neue, besonders vorteilhafte Ausbildung eines derartigen Rekuperators. There are recuperators known at. which are inserted into the air ducts storage body are, so that the recuperators also act as heat accumulators without there is a deterioration in the heat transfer between the exhaust gas flow and the air flow. Such recuperators are important, for example, for heating flame furnaces, because after each batch ίο results in a substantial decrease in the exhaust gas temperature, so that in itself also the Preheating of the air or des-. Gases, is decreased while just in this period the preheating of special. Meaning is. The storage effect "of the recuperators has a balancing effect here. The. "The invention relates to a new, particularly advantageous Training of such a recuperator.

äo Nach der Erfindung werden 'die zur Bildung der Luftkanäle in bekannter Weise eingefügten Speicherkörper von I- oder U"förmigem Querschnitt so zwischen die Abgaskanäle eingefügt, daß ihre Aussparungen den Abgasa5 kanälen zugekehrt sind und somit an den Wänden der Abgaskanäle liegende Luftkanäle' bilden. An sich, ist es bekannt, T- oder U-förmige Steine beim Aufbau der Luftkanäle von Rekuperatoren zu verwenden. Dabei sind aber die Stege der Profilsteine senkrecht zu den Wänden der Abgaskanäle gerichtet, so daß sie diese miteinander verbinden, während die Aussparungen Luftkanäle bilden, die in der Mitte zwischen den Abhitzekanälen und von diesen durch die Hauptmasse der Profilsteine getrennt liegen. Im Gegensatz hierzu bieten die gemäß der Erfindung ausgebildeten Rekuperatoren den Vorteil, daß sich die Speichermasse der Profilsteine innerhalb des Luftkanals befindet, also von der Luft umgeben ist, die im übrigen unmittelbar an den Wänden der"Äbhitzekanäle' entlang strömt. Die hoch erhitzten Wände der Abhitzekanäle übertragen daher die Wärme unmittelbar auf die Luft und erhitzen auß.erdem die in den Luftkanälen- ihnen gegenüberstehende Speichermasse durch Strahlung. Vor den bekannten· Rekuperatoren, die innerhalb der Luftkanäle Speicherkörper enthalten, besteht der wesentliche Vorteil eines einfacheren und widerstandsfähigen Aufbaues des Gesamtrekuperators 'aus normalen, leicht herzustellenden Formsteinen,According to the invention, they become 'education the air ducts inserted in a known manner storage body of I or U "shaped Cross-section inserted between the exhaust ducts so that their recesses meet the exhaust gas a5 ducts are facing and thus air ducts lying on the walls of the exhaust ducts' form. In itself, it is known to use T- or U-shaped stones when building the air ducts To use recuperators. But the webs of the profile blocks are perpendicular to the Walls of the exhaust ducts directed so that they connect them together while the Recesses form air ducts in the middle between the waste heat ducts and from these are separated by the main mass of the profile stones. In contrast, offer the recuperators designed according to the invention have the advantage that the storage mass the profiled stones are located within the air duct, so it is surrounded by the air that is otherwise directly on the walls the "heat ducts" flows along Highly heated walls of the waste heat ducts therefore transfer the heat directly the air and also heat the air in the air ducts opposite them Storage mass from radiation. In front of the well-known recuperators that operate within the Containing air ducts storage body, the main advantage is a simpler and Resistant structure of the overall recuperator from normal, easy-to-manufacture Shaped stones,

Durch die Kanäle 1 von kreisförmigem Querschnitt der Kanalsteine 2 werden in bekannter Weise die Verbrennungsgase geleitet. Zwischen den einzelnen Kanalsteinreihen 2 sowie diesen und den Ofenwänden 6 liegen die Luftkanäle 4, die von den Aussparungen der Speicherkörper 3, 7 von I- bzw. U-förmigem Querschnitt gebildet werden. Die den Speichersteinen gegenüberliegenden dünnen Wandungen der Kanalsteine 2 erhitzen unmittelbar die Luft und außerdem durch Strahlung die der Speichersteine 3, 7, so daß in diesen erhebliche Wärmemengen aufgespeichert werden.Through the channels 1 of circular cross-section of the channel stones 2 are known in Way the combustion gases passed. Between the individual rows of canal stones 2 as well as these and the furnace walls 6 are the air channels 4, which are from the recesses of Storage body 3, 7 of I- or U-shaped Cross-section are formed. The thin walls opposite the storage stones the channel stones 2 directly heat the air and also through radiation that of the storage stones 3, 7, so that considerable amounts of heat are stored in them will.
