Description
Die Erfindung betrifft eine Einrichtung zum gleichmäßigen Erhitzen langer Heizrohre durch Verbrennen eines Gas-Luft-Gemisches. in den Heizrohren., in deren Einlaßende zwischen dem eintretenden Gas und. Luftstrom zwecks Hinauszögerung der Verbrennung ein Strom von ringförmigem Querschnitt eines nicht brennbaren Gases miteingeführt wird und an deren Auslaßende zur Vera hinderung des Auftretens eines Rückstanesi eine Absaugeinrichtung vorgesehen ist.The invention relates to a device for uniform heating long heating pipes by burning a gas-air mixture. in the heating pipes., in its inlet end between the entering gas and. Air flow for the purpose of delaying Combustion is a stream of annular cross-section of a non-combustible gas is also introduced and at the outlet end to prevent the occurrence of a Vera Rückstanesi a suction device is provided.
Bekanntlich ist die Förderleistung eines Ventilators der Dichte der geförderten Luft proportional und deshalb umgekehrt proportional der Temperatur der in den Ventilator einströmenden Luft. Demgemäß wird bei jeder Temperaturänderung der in den; Ventilator einströmenden Luft auch die Ansaugleistung des Ventilators gewichtsmäßig verändert. Bei der eingangs genannten Einrichtung, bei der die Absaugvorrichtung den doppelten Zweck hat, die Verbrennungsgase aus dem von innen .beheizten Heizrohr abzusaugen uud gleichzeitig das von dem Brenner benötigte Gas für die Verbrennung anzusaugen, wird sich eine Temperaturänderung so auswirken, daß bei steigender Temperatur der Abgase die Menge des vom Ventilator angesaugten Gases, auf das Gewicht bezogen, geringer wind, mit der gleichzeitigen Wirkung, daß die Menge des dem Brenner zur besseren Verbrennung zugeführten Sauerstoffes sich ebenfalls verringert. Das bedeutet, daß das Verhältnis der Luft zum Gäs fällt, je nachdem, wie die Absaugung fällt. oder die Temperatur der aus dem Heizrohr abgesaugten Abgase steigt.As is well known, the flow rate of a fan is the density of the conveyed air proportionally and therefore inversely proportional to the temperature the air flowing into the fan. Accordingly, with every change in temperature the in the; Fan inflowing air also affects the suction capacity of the fan changed in weight. In the device mentioned at the beginning, in which the suction device Has the dual purpose of removing the combustion gases from the heating pipe, which is heated from the inside suction and at the same time the gas required by the burner for the combustion suction, a change in temperature will have such an effect that as the temperature rises of exhaust gases is the amount of gas sucked in by the fan, based on weight, low wind, with the simultaneous effect that the amount of the burner to the The oxygen supplied to better combustion is also reduced. That means, that the ratio of air to gas falls, depending on how the suction falls. or the temperature of the exhaust gases extracted from the heating pipe rises.
In Wärmebehandlungsöfen, bei denen. die Schwankung der Arbeitstemperatur erhebliche ist, wie z. B. Öfen, welche für zwei oder mehrere Wärmuorgänge mit verschiedenen Arbeitstemperaturen betrieben werden, ist die Beibehaltung des: jeweils erforderlichen Luft-,Brennstoff-Gewichtsverhältnisses ohne Nachregulierung des Brenners von großer Bedeutung. .In heat treatment furnaces where. the fluctuation in working temperature is significant, such as B. Ovens, which for two or more Wärmuorgänge with different Operating temperatures are maintained, the maintenance of the: required in each case Air to fuel weight ratio without readjustment of the burner of great Meaning. .
Um die Temperatur im Ansaugquerschnitt der Ansaugvorrichtung des. zu fördernden Abgases zu verringern und damit die Förderleistung, bezogen auf das Gewicht, zu vergrößern und weiter die unter der Wirkung der Absaugvorrichtung in das Heizrohr eintretende Luftgewichtsmenge im Sinne eines gleichbleibenden Verhältnisses in Abhängigkeit von der Förderleistung der Absaugvorrichtung zu brinr gen, wird gemäß der Erfindung vorgeschlagen, bei eingangs genannten Einrichtungen einen Wärmeaustauscher zur Vorwärmung der Luft kurz vor Austritt der Abgase aus dem Heizrohr vorzusehen. Durch die Abkühlung der Abgase wird die Ansaugleistung des Ventilators gewichtsmäßig gesteigert, so daß mehr Gas in das Heizrohr eintritt, als dies der Fall sein, würde, wenn, die Abgase nicht abgekühlt werden. Die Erwärmung der Luft durch den Wärmeaustausch dehnt dieselbe aus und schafft so einen Ausgleich für die verringerte Menge Gas, welche in das- Heizrohr eingesaugt wird, wenn die Ansaugleistung des Ventilators zurückgeht. Zweckmäßig werden diese Vorgänge durch entsprechende Regelorgane automatisch überwacht.To determine the temperature in the intake cross-section of the intake device of the. to reduce the exhaust gas to be conveyed and thus the delivery rate, based on the Weight, to increase and further the under the action of the suction device in the air weight entering the heating pipe in the sense of a constant ratio depending on the delivery rate of the suction device proposed according to the invention, a heat exchanger in the aforementioned devices to preheat the air shortly before the exhaust gases exit the heating pipe. As the exhaust gases cool down, the suction capacity of the fan increases in weight increased so that more gas enters the heating tube than would be the case, if, the exhaust gases are not cooled. The warming of the air through heat exchange expands it and thus compensates for the reduced amount of gas, which is sucked into the heating pipe when the suction power of the fan going back. Appropriately, these processes are carried out automatically by appropriate regulating bodies supervised.
Die Zeichnung veranschaulicht den Gegenstand der Erfindung in einem Ausführungsbeispiel, und zwar Abb. i als Seitenansicht im. senkrechten Schnitt, Abb. z als Teilansicht der Abb. i, Abb. 3 als Schnitt durch: einen Brenner in Verbindung mit dem Einlaßende des Heizrohres.The drawing illustrates the subject matter of the invention in one Embodiment, namely Fig. I as a side view in. vertical cut, Fig. Z as a partial view of Fig. I, Fig. 3 as a section through: a burner in connection with the inlet end of the heating pipe.
Es bedeutet a eine Mauer der Ofenkammer, in der ein brennstoffbeheiztes Heizrohr b angeordnet ist. Das Heizrohr ist im Beispiel haarnadelförmig und ragt mit seinen freien Enden ausi der Ofenkammer durch die Wand a heraus. Das Heizrohr b wird durch einen Brenner c bekannter Bauart beheizt. Mit dem Absaugende des Heizrohres ist eine Absaugleitung verbunden, bestehend aus einem Krümmer d und einem Rohr e, an welches sich der Absaugventilator f anschließt. Das Absaugrohr e ist innen und außen mit wärmeleitenden Rippen g und g1 versehen. Ferner ,ist das Absaugrohr von einem Gehäuse h umgeben, welches an seinem oberen Ende offen ist und an seinem unteren Ende mit dem Birenner-c in Verbindung steht.It means a wall of the furnace chamber in which a fuel-heated heating pipe b is arranged. The heating tube is hairpin-shaped in the example and protrudes with its free ends from the furnace chamber through the wall a. The heating tube b is heated by a burner c of known design. A suction line is connected to the suction end of the heating pipe, consisting of a bend d and a pipe e, to which the suction fan f is connected. The suction pipe e is provided inside and outside with heat-conducting ribs g and g1. Furthermore, the suction pipe is surrounded by a housing h which is open at its upper end and which is connected to the bulb-c at its lower end.
DieLuft tritt durch das obereEnde des Gehäuses h ein, erwärmt sich an den; Rippen g1 und wird so in vorgewärmtem Zustand dem Brenner c zugeführt.The air enters through the upper end of the housing h, heats up to the; Ribs g1 and is thus fed to the burner c in a preheated state.
