摘要:
The reheat burner (1) comprises a channel (2) with a lance (3) projecting thereinto to inject a fuel over an injection plane (4) perpendicular to a channel longitudinal axis (15). The channel (2) and lance (3) define a vortex generation zone (6) upstream of the injection plane (4) and a mixing zone (9) downstream of the injection plane (4) in the hot gas (G) direction. The mixing zone (9) has a cross section with diverging side walls (20) in the hot gas (G) direction. The diverging side walls (20) define curved surfaces in the hot gas (G) direction having a constant radius (R).

The invention relates to a device for generating an aerosol jet (11) of fuel, which after ignition can be used as a working flame. The device comprises a fuel tank filled with a pressurized combustible medium, a spring-loaded actuating valve, which selectively opens and closes the outlet opening of the fuel tank, and an attachment that is connected to the outlet opening of the fuel tank and includes the actuating valve and an outward-directed tubular extension (10). In order to be able to use such a device using controlled stable flames, even under critical operating conditions, according to the invention, the end of the extension is connected to an air-heating mixing combustion chamber (20), which encompasses the aerosol jet (11) discharged from the extension (10) on all sides with air. Furthermore, when the actuating valve is open, the air-heating mixing combustion chamber (20) sucks in air through the aerosol jet (11) and the internal side of the air-heating mixing combustion chamber (20), and the sucked-in air mixes with the aerosol jet emerging from the extension (10).

A burner includes a generally cylindrical reactor chamber (1) including a housing (1′) having a proximal end (1p) and a distal end (1d). In the distal end of the reactor chamber (1) there is provided a catalyst (4). A fuel inlet (7) is provided in the proximal end of the reactor chamber. There are also a plurality of air inlets (22, 23; 24) arranged in the reactor wall at the proximal end. The inlets are configured to provide a rotating flow of the air injected into the reactor chamber. There is also provided a flow homogenizer (8; 30) extending over the cross-section of the reactor chamber at a position between the fuel inlet (7) and the catalyst (4).

A multiple cone burner (1) comprising a swirl chamber (2) with conical airfoil elements (7) having fuel nozzles (12) at the pressure side (18) and/or at the suction side (19) and/or at the trailing edge (20), a lance (3) in the swirl chamber (2), a transition element (22) at the larger end of the swirl chamber (2), and a mixing tube (23) connected to the transition element (22) providing an almost completely circular air passage (24) between the transition element (22) and the mixing tube (23). Through the air passage (24), additional air is ejected into the mixing tube (23) substantially parallel to the inner mixing tube surface and axis (5).

Die Erfindung betrifft einen Ölvormischbrenner mit einem im Wesentlichen zylindrischen Brennelement (1), einer Brenneroberfläche (2) auf der äußeren Mantelfläche, einem stirnseitigen Deckelelement (3) am freien Ende, einer Verteilkammer (4) unterhalb der Brenneroberfläche (2), einer zentralen, auf der Längsachse des Brennelementes (1) angeordneten Zerstäubungseinrichtung (5), insbesondere ein Einspritzventil oder eine Öldüse, einem an ein stromaufwärts angeordnetes Gebläse angeschlossenen Verbrennungsluftkanal (6) sowie einem Luftwärmetauscher (7) unterhalb der Brenneroberfläche (2) für die Vorwärmung mindestens eines Teilstroms der Verbrennungsluft. Aufgabe der Erfindung ist es, bei einem Ölvormischbrenner die Verbrennungsqualität und die Robustheit, besonders im Hinblick auf Modulationsfähigkeit, zu optimieren. Erfindungsgemäß ist daher vorgesehen, dass ein Prallkörper (8) auf der Längsachse des Brennelementes (1), im direkten Bereich des Flüssigkeitsstrahles mit Abstand vor der Zerstäubungseinrichtung (5) angeordnet ist.
摘要:
The invention relates to a premix burner comprising a spin generator (1) and a mixing tube (2) mounted downstream for the combustion of gaseous (13) and liquid (39) fuel which is introduced into the inner burner space (16) of the spin generator (1) and/or along a burner axis (12) into the inner burner space (16) of the spin generator (1), during the admission of the combustion air (4). Said premix burner also comprises a fuel lance (15) arranged on the burner axis (12). The premix burner according to the invention is characterised in that the transition region (6, 8, 40) from the spin generator (1) to the mixing tube (2) comprises at least one additional supply (18, 19, 22) for the introduction of gaseous and/or liquid premix fuel from the wall region into the inner burner space (17) of the mixing tube (2).
