Abstract

The gas burner is for a domestic cooker. It is constructed from three coaxial hollow cylinders to form two co-axial annular chambers (2). Each annular chamber (2) has a supply pipe (1) for a mixture of gas and primary air. The inner wall of the inner annular chamber has a row of radial holes (3) near its upper end. These holes direct has flames radially inwards and these flames are supplied with secondary combustion air by an upward current which flows through the central vertical duct. The outer wall of the outer annular chamber has a row of holes which direct the flames radially outwards. These flames are supplied with secondary combustion air from the surrounding atmosphere. USE - Domestic gas cooker burner system.

Description

Die Erfindung betrifft einen Gasbrenner mit vorgegebener, möglichst gleichmäßiger Wärmeflußverteilung an den Boden des Gefäßes, insbesondere für Haushaltsherde und -kocher.The invention relates to a gas burner with a predetermined, if possible even heat flow distribution to the bottom of the Vessel, in particular for domestic stoves and cookers.

Bei möglichst großem Wirkungsgrad wird ein niedriger CO- und N x O y -Gehalt im Abgas angestrebt, da der Gasbrenner in geschlossenen Räumen ohne Abgasabzug in Betrieb sein soll.With the highest possible efficiency, a low CO and N x O y content in the exhaust gas is aimed for, since the gas burner should be operated in closed rooms without exhaust gas extraction.

Zur wirtschaftlichen Nutzung der Gasbrenner ist es vorteilhaft, die abgegebene Leistung in möglichst vielen Stufen regeln zu können.For economical use of the gas burner, it is advantageous regulate the output in as many stages as possible can.

Es ist bekannt, daß zur Erfüllung dieser Erfordernisse divergente Gasbrenner verwendet sind.It is known that divergent to meet these needs Gas burners are used.

Bei den herkömmlichen Gasbrennern war die Regelbarkeit der abgegebenen Leistung auf zwei Stufen begrenzt.With conventional gas burners, the controllability of the dispensed was Performance limited to two levels.

Es ist erwünscht, die Leistung im Sparbetrieb so niedrig wie möglich zu halten.It is desirable to save as little power as possible to keep possible.

Es besteht die Möglichkeit, den Wirkungsgrad sowie die Regelbarkeit zu verbessern.There is the possibility of efficiency and controllability to improve.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Flamme in zwei verschiedenen Faszikeln verteilt ist: ein konvergenter und ein divergenter Faszikel.The object is achieved in that the flame is distributed in two different fascicles: a convergent and a divergent fascicle.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Wärmeflußverteilung am Boden der Gefäße gleichmäßig wird, dadurch erhöht sich der Wirkungsgrad.The advantages achieved with the invention are in particular that the heat flow distribution at the bottom of the vessels becomes even, this increases the efficiency.

Da der Brenner aus zwei getrennten Faszikeln besteht, die getrennt regelbar sind, ergibt sich eine Vielzahl der Regelstufen, so läßt sich die Leistung im Sparbetrieb auf bedeutend weniger als 30% der Nennleistung verringern.Because the burner consists of two separate fascicles, which are separate are controllable, there are a variety of control levels, so lets performance in economy mode is significantly less than 30% reduce the nominal power.

Ein Ausführungsbeispiel der Erfindung ist in der Abb. 1 dargestellt. Der abgebildete Brenner ist aus Blechteilen zusammengeschweißt, ist jedoch auch aus anderen Materialien und mit anderen Technologien (z. B. Gießverfahren) herstellbar. Die Abb. 2 zeigt eine andere Form von Gasbrenner.An embodiment of the invention is shown in Fig. 1. The burner shown is welded together from sheet metal parts, but can also be made from other materials and with other technologies (e.g. casting process). Fig. 2 shows another form of gas burner.

Die Symmetrieachsen der Ausflußöffnungen in Abbildungen schließen einen 90°-Winkel mit der Symmetrieachse des Gasbrenners ein, können aber ±80° davon abweichen. Close the axes of symmetry of the outflow openings in the figures a 90 ° angle with the symmetry axis of the gas burner but deviate from it by ± 80 °.  

Das auf der Abb. 1 mit (1) bezeichnete Rohr ist ein bekanntes Venturirohr, in dem zum gasförmigen Brennstoff die Primärluft gemischt wird. Nach dem Verlassen des Venturirohrs strömt das Gas in einen ringförmigen Raum (2), der das Gas zu den Ausströmungsöffnungen (3) verteilt.The tube labeled ( 1 ) in Fig. 1 is a known Venturi tube in which the primary air is mixed with the gaseous fuel. After leaving the Venturi tube, the gas flows into an annular space ( 2 ) which distributes the gas to the outflow openings ( 3 ).

Die Sekundärluft des konvergenten Teils des Brenners wird der Flamme durch das Innere des Brenners durch das mit (4) bezeichnete Rohr zugeführt. Die Sekundärluft des divergenten Teils des Brenners wird der Flamme wie bei gewöhnlichen Gasbrennern zugeführt.The secondary air of the convergent part of the burner is supplied to the flame through the inside of the burner through the tube labeled ( 4 ). The secondary air of the divergent part of the burner is fed to the flame as with ordinary gas burners.

Die Abb. 2 zeigt die Draufsicht eines Brenners, der analog zu dem auf Abb. 1 aufgebaut ist und mit Zündflamme für innere und äußere Flammenkrone vorgesehen ist. Fig. 2 shows the top view of a burner, which is constructed analogously to that in Fig. 1 and is provided with pilot light for the inner and outer flame crown.
