Abstract

The flame tube is closed at one end and is for use in gas firing systems. The fuel gas is burnt completely and uniformly over the burning surface. The combustion process is improved by providing the central flue gas tube (3) with guiding blades. The guide blades (4) project radially from the shell of the flue gas pipe (3). These guide blades are arranged at different angles relative to the gas stream. The flue gas reaches from the open end close to the closed end wall. Combustion takes place directly within the outside tube.

Description

STRAHLHEIZROHR FÜR GASBEHEIZUNG. RADIANT HEATING TUBE FOR GAS HEATING.

a~=~~~~~~~ ~ ~~~=== Vorl. Schrift betrifft ein Strahlheizrohr für Gasbeheizung, dessen in den Ofen hineinragende Stirnseite geschlossen ist, während durch die offene, aus dem Ofen herausragende Stirnseite das Brenngas und die Verbrennungsluft zugeführt und das Abgas abgeführt wird. a ~ = ~~~~~~~ ~ ~~~ === preliminary Scripture relates to a radiant heating tube for Gas heating, the end of which protruding into the furnace is closed, while the fuel gas and the combustion air through the open end protruding from the furnace supplied and the exhaust gas is discharged.

Das heute in dieser Form hauptsächlich verwendete Strahlheizrohr fur Gasbeheizung ist das Mafltelstrahlheizrohr, welches durch die Verbrennung des Gases im Brennrohr eine geminderte wirtschaftlichkeit hat.The radiant heating tube mainly used in this form today for Gas heating is the Mafltelstrahlheizrohr, which by burning the gas has a reduced profitability in the combustion tube.

Gegenstand vorl. Erfindung ist das Strahlheizrohr mit in seiner Mittelachse befindlichem Abgasrohr, welches von der offenen Stirnseite bis kurz vor der geschlossenen Stirnseite reicht und im Bereich der Brennlänge mit etwa rechtwinklig abstehenden Schaufeln versehen ist, wobei die Verbrennung direkt im äußeren Rohr stattfindet.The subject of the present invention is the radiant heating tube with in its central axis located exhaust pipe, which from the open face to shortly before the closed The front side is sufficient and in the area of the focal length with protruding approximately at right angles Shoveling is provided, with the combustion taking place directly in the outer tube.

Die Schaufelflächen stehen entweder parallel zur Strahlrohrachse oder spitzwinklig dazu mit dem ErPolg, daß die Verbrennung des Gases mit der gewollten Intensität auf die Heizlänge des Strahlrohres erfolgt.The blade surfaces are either parallel to the nozzle axis or at an acute angle to it with the result that the combustion of the gas with the desired Intensity on the heating length of the radiant tube takes place.

Das Strahlheizrohr nach vorl. Erfindung ist beispielsweise in beil. Zeichnung: Fig. 1 stellt es im Längsschnitt, Fig. 2 im Querschnitt dar. Das Außenrohr 1 durchdringt die Ofenwand 2.The radiant heating tube according to the present invention is for example in attach. Drawing: Fig. 1 shows it in longitudinal section, Fig. 2 in cross section. The outer tube 1 penetrates the furnace wall 2.

In der Längsachse des Außenrohres 1 ist das Abgasrohr 3, welches in einigem Abstand vor der Kuppel 7 des Außenrohres 1 endet. Im Wandteil des Außenrohres 1 ist das Luftrohr 5, welches mit dem Außenrohr 1 den Luftleitkanal 8 bildet. Auf den beiderseitigen Flächen des Luftrohre 5 sind Wärmeleitrippen 9, welche die Übertragung der Abgaswärme auf die Luft verbessern. Die Luft strömt durch den ringförmigen Kanal 10, der das Zuführungsrohr 11 hat. Das Gas wird durch das Rohr 12 zu dem Ringkanal 13 und von dort zur Verbrennung durch die Rohre 14 geführt. In Fig. 2 sind die Querschnitte des Außenrohres 1 und des Abgasrohres 3, verbunden mit den Schaufeln 4, zu ersehen. Die Schaufeln 4 können die in Fig. 3 dargestellte gleichmäßige Schrägstellung zur Achse der Rohre 1 und 3 haben, so daß die Brenngase einen Drall um das Abgasrohr 3 erhalten. Bei der in Fig. 4 dargestellten Stellung stehen die Schaufeln 4 parallel zur Längsachse der Rohre 1 und 3 und bewirken lediglich eine Wirbelung durch ihre Dicke.In the longitudinal axis of the outer pipe 1 is the exhaust pipe 3, which in Some distance in front of the dome 7 of the outer tube 1 ends. In the wall part of the outer pipe 1 is the air pipe 5 which, together with the outer pipe 1, forms the air duct 8. on the two-sided surfaces of the air tubes 5 are heat conducting fins 9, which the transmission the exhaust heat to improve the air. The air flows through the annular channel 10 having the feed pipe 11. The gas becomes the annular channel through the pipe 12 13 and from there passed through the pipes 14 for combustion. In Fig. 2 are the cross-sections of the outer pipe 1 and the exhaust pipe 3, connected to the blades 4, can be seen. The blades 4 can be shown in Fig. 3 uniform inclination to Axis of tubes 1 and 3 have so that the combustion gases swirl around the exhaust pipe 3 received. In the position shown in FIG. 4, the blades 4 are parallel to the longitudinal axis of the tubes 1 and 3 and only cause a vortex through their Thickness.

In Fig. 5 sind die Schaufeln 4 unter sich verschieden winklig gestellt, so daß eine starke Wirbelung des Brenngases erzeugt vird. Der im Einlauf mit der Breite a und dem AuPlauf b verlangsamte Gasstrom wird von dem daneben befindlichen Gasstrom mit der Einlaufbreite d und der Auslaufbreite e infolge dessen größerer Geschvindigkeit aufgerieben und vervirbelt.In Fig. 5, the blades 4 are set at different angles under each other, so that a strong vortex of the fuel gas is generated. The one in the inlet with the Width a and the flow b, slowed down gas flow is from the one located next to it Gas flow with the inlet width d and the outlet width e as a result of this greater Velocity worn out and whirled.

Das beschriebene Strahlheizrohr ist geeignet, das Heizgas vollständig und gleichmäßig auf seine Heizlänge zu verbrennen. Die Wirtschaftlichkeit ist größer als bei dem Mantelstrahlheizrohr, weil die Verbrennungswärme direkt auf das Außenrohr 1 wirkt und das Brenngas zur vollständigen Verbrennung gebracht vird.The radiant heating tube described is suitable for the heating gas completely and burn evenly over its heating length. The economy is greater than with the jacket radiant heating tube, because the heat of combustion directly on the outer tube 1 acts and the fuel gas is brought to complete combustion.
