Definitions
- the invention relates to a fuel gas distributor for a multi-stage burner, preferably for heaters.
- Multi-stage burners are known in the art to extend the modulation range of burners.
- individual burner areas are switched on or off.
- each burner segment has its own fuel gas distributor tube and in each case a separate gas fitting.
- Out FR 2 800 848 A a multi-segment burner is known in which individual areas can be switched on and off by opening and closing valves in the gas fitting.
- JP 58 221315 A discloses a gas valve with multiple valves, which allows a staggered gas supply to hereby be able to control the fuel gas flow rate stepped.
- DE 196 05 508 A1 shows a fuel gas manifold with two fuel gas lines. Two separate gas fittings are each connected to one of the two lines. Fuel gas nozzles are alternately connected to a fuel gas line. Due to the separate control of the gas fittings thus two areas of an atmospheric injector burner can be operated independently.
- the invention has for its object to provide a fuel gas manifold, which is characterized by compactness and cost savings.
- the integration into a component allows a compact design.
- the manifold is an extrusion valve. This makes it particularly easy to produce the manifold.
- the gas lines are separated by valves. In this way it can be achieved that at least one gas line can be switched off or switched on.
- the above-mentioned gas fitting with two outputs can be dispensed with and the connection or disconnection - with all advantages and disadvantages - take place directly at the distributor.
- the valve is arranged on the side of the valve tube.
- the distributor pipe according to the invention serves for the separate supply of the fuel gas to at least two areas.
- valve body is in or at an opening between the gas lines.
- valve body may be disposed within the valve tube.
- the gas connection can take place laterally in the direction of the extension line of the distributor tube or also perpendicular thereto through the distributor tube.
- FIG. 1 shows a gas fitting 40 with a fuel gas inlet 41 and two fuel gas outlets 42, 43.
- a valve body 45 of an inlet valve 44 is arranged in the flow direction behind the fuel gas inlet 41.
- Two valve bodies 47, 49 of two outlet valves 46, 48 follow in the flow direction. The transition to the two fuel gas outlets 42, 43 is blocked or opened by the valve bodies 47, 49.
- FIG. 1 the state is shown that both the inlet valve 44 and the exhaust valves 46, 48 are closed, whereby no fuel gas from the fuel gas inlet to one of the fuel gas outlets 42, 43 can flow.
- FIG. 2 shows the same gas valve 40, wherein both the inlet valve 44 and the exhaust valves 46, 48 are opened, whereby fuel gas from the fuel gas inlet 41 to the two fuel gas outlets 42, 43 can flow.
- FIG. 3 shows the identical gas valve in the operating case in which the power is modulated. The inlet valve 44 is open, the outlet valve 46 is open, and the outlet valve 48 is closed. As a result, fuel gas flows from fuel gas inlet 41 to the fuel gas outlet 42, through the fuel gas outlet 43 can flow no fuel gas.
- the intake valve 44 is open, the exhaust valve 46 is closed and the exhaust valve 48 is opened. Now, fuel gas can escape from the fuel gas outlet 43, while no fuel gas can flow through the fuel gas outlet 42.
- the performance can be significantly influenced. For example, if one burner is twice as large as the other, then one-third of the modulation power can be covered by the small burner and smaller power by the modulation of this Brenners, while at two-thirds power the larger burner is operated and the smaller is switched off. As a result, a very large bandwidth is possible.
- FIG. 5 shows a distributor tube 10 according to the invention with gas nozzles 8 and fuel gas connections 19, 20.
- the distributor tube 10 extends along an extension line 15, which corresponds to an extrusion profile of the extrusion direction.
- FIG. 6 shows the same manifold 10 with two internal gas lines 11, 12.
- FIG. 7 shows that the gas line 11 is connected via a connecting bore 13 with a fuel gas nozzle 8.
- FIG. 8 shows the same manifold 10 at a different location at which the gas nozzle 8 is connected via a connecting bore 14 with the gas line 12. This makes it possible, for example, to connect fuel gas nozzles 8 alternately to one gas line 11 and then to the other gas line 12.
- FIG. 6 shows the same manifold 10 with two internal gas lines 11, 12.
- FIG. 7 shows that the gas line 11 is connected via a connecting bore 13 with a fuel gas nozzle 8.
- FIG. 8 shows the same manifold 10 at a different location at which the gas nozzle 8 is connected via a connecting bore 14 with the gas line 12. This makes
- FIG. 9 shows a non-inventive manifold with a valve 16 which has a valve body 17 which can close an opening 18 between the gas line 11 and the gas line 12.
- the valve can be seen in the open state
- FIG. 10 the same valve can be seen in the same manifold in the closed state.
- FIG. 11 a valve 16 laterally disposed on the manifold 10.
- FIG. 11 is the valve body 17 in a position which releases a connection between the gas line 11 and the gas line 12.
- the valve is in the FIG. 12 closed.
- FIG. 13 shows a fuel gas connection 20, which ensures that the gas line 12 can be supplied in the manifold 10 with fuel gas.
- a combination of a gas fitting 40 with a manifold 10 according to the invention is not explicitly shown. It makes sense to operate the manifold 10 without valve body 17 between the gas lines 11, 12, but instead each one of the fuel gas outlet 42, 43 of the gas fitting 40 to connect each with a gas lines 11, 12 of the manifold 10 and the ends of the gas lines eleventh 12, to which no fuel gas connections 19, 20 are attached, to be sealed.

Mehrstufige Brenner sind gemäß dem Stand der Technik bekannt, um den Modulationsbereich von Brennern auszuweiten. Hierbei werden einzelne Brennerbereiche zu- bzw. abgeschaltet. Gemäß dem Stand der Technik verfügt jedes Brennersegment über ein eigenes Brenngas-Verteilerrohr und jeweils eine gesonderte Gasarmatur.Multi-stage burners are known in the art to extend the modulation range of burners. Here, individual burner areas are switched on or off. According to the prior art, each burner segment has its own fuel gas distributor tube and in each case a separate gas fitting.
Aus
Der Erfindung liegt die Aufgabe zugrunde, ein Brenngas-Verteilerrohr zu schaffen, die sich durch Kompaktheit und Kostenersparnis auszeichnet.The invention has for its object to provide a fuel gas manifold, which is characterized by compactness and cost savings.
Erfindungsgemäß wird dies dadurch erreicht, dass in dem Verteilerrohr mindestens zwei Gasleitungen integriert sind. Die Integration in ein Bauteil ermöglicht eine kompakte Bauweise. Bei dem Verteilerrohr handelt es sich um ein Strangpressventil. Hierdurch lässt sich das Verteilerrohr besonders einfach herstellen. Die Gasleitungen sind mittels Ventilen voneinander getrennt. Hierdurch kann erreicht werden, dass mindestens eine Gasleitung ab- oder zugeschaltet werden kann. Somit kann optional auf die vorgenannte Gasarmatur mit zwei Ausgängen verzichtet werden und die Zu- beziehungsweise Abschaltung - mit allen Vor- und Nachteilen - direkt am Verteiler erfolgen. Das Ventil ist seitlich am Ventilrohr angeordnet. Das erfindungsgemäße Verteilerrohr dient der getrennten Zuführung des Brenngases auf mindestens zwei Bereiche.According to the invention this is achieved in that at least two gas lines are integrated in the manifold. The integration into a component allows a compact design. The manifold is an extrusion valve. This makes it particularly easy to produce the manifold. The gas lines are separated by valves. In this way it can be achieved that at least one gas line can be switched off or switched on. Thus, optionally, the above-mentioned gas fitting with two outputs can be dispensed with and the connection or disconnection - with all advantages and disadvantages - take place directly at the distributor. The valve is arranged on the side of the valve tube. The distributor pipe according to the invention serves for the separate supply of the fuel gas to at least two areas.
