Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf einen mehretagigen gasbeheizten Backofen mit einer unten angeordneten Brennerkammer, einem hinter der mit Heizgas-Einström-Öffnungen zu den einzelnen Backräumen versehenen Backraumrückwand innerhalb des Ofenblocks aufsteigenden Heizgas-Steigschacht und einem hinter den Ofentüren, also auf der Ofenfrontseite angeordneten, die Verbrennungsgase zum Gasauslaß führenden Heizgas-Fallschacht.The invention relates to a multi-level gas-fired oven with a bottom Burner chamber, one behind the one provided with heating gas inflow openings to the individual baking chambers Back wall of the baking chamber inside the furnace block rising hot gas riser shaft and one behind the furnace doors, that is to say arranged on the front of the furnace, leading the combustion gases to the gas outlet Heating gas chute.
Um auch bei ungünstigen Schornsteinverhältnissen und an S chi echt wettertagen mit ungünstigem Zug trotzdem derartige ziemlich beträchtliche Strömungswiderstände aufweisende Backöfen störungsfrei betreiben zu können, soll zum Zwecke der natürlichen Zugbegünstigung gemäß der Erfindung innerhalb des erwähnten Steigschachtes. und zwar symmetrisch zur Mittellängsebene des Ofenblocks, ein die Verbindung zwischen dem unteren Ende des Fallschachtes oberhalb des Brenners und dem oberen Abgasstutzen des Ofenblocks herstellender Abgaskanal angeordnet werden, der durch die Brennergase von außen beheizt wird. Die dadurch entstehenden Wärmeverluste können im Hinblick auf die auf diese Weise zu erreichende Zugbegünstigung in Kauf genommen werden.Even with unfavorable chimney conditions and on s chi real weather days with unfavorable drafts nevertheless operate such ovens exhibiting fairly considerable flow resistances without interference to be able to, should for the purpose of natural train preferential treatment according to the invention within the mentioned riser shaft. namely symmetrically to the central longitudinal plane of the furnace block, a connection between the lower end of the chute above the burner and the upper exhaust port of the Furnace blocks producing exhaust duct are arranged, which is heated from the outside by the burner gases will. The resulting heat losses can be achieved with regard to the in this way Discounted trains are accepted.
Ein Ausführungsbeispiel eines erfindungsgemäßen Ofens ist aus der Zeichnung ersichtlich, in derAn embodiment of a furnace according to the invention can be seen from the drawing, in which
Fig. 1 einen parallel zur Ofenfront geführten senkrechten Schnitt durch einen Mehretagenofen,1 shows a vertical section, parallel to the furnace front, through a multi-opening furnace,
Fig. 2 einen senkrechten Mittellängsschnitt durch den Ofen, den Abgaskanal jedoch nicht geschnitten, sondern in seitlicher Ansicht,2 shows a vertical central longitudinal section through the furnace, but the exhaust gas duct is not cut, but in a side view,
Fig. 3 einen Horizontalschnitt durch einen Backraum, auf das Ofenfrontgebiet beschränkt nach Linie a-b (Fig. 2), undFig. 3 shows a horizontal section through a baking chamber, limited to the oven front area according to line from (Fig. 2), and
Fig. 4 die Anordnung einer ,Sicherheits- und Anheizklappe am Abgaskanal mit einem Bimetall-Schließorgan zeigen.4 shows the arrangement of a safety and heating flap show on the exhaust duct with a bimetal closing element.
Die für sich selbst sprechende Zeichnung läßt einen Ofenblock mit vier übereinander angeordneten Backräumen erkennen, denen die Brennerabgase aus dem Mehrröhrenbrenner 5 durch je zwei aus Fig. 1 ersichtliche Öffnungen in der Backraumrückwand hinten zuströmen, während sie in einem hinter den Ofentüren angeordneten Fallschacht 2 wieder vereinigt werden. Der Heizgas- Steigschacht 1 hinter den Backräumen wird durch einen von dem unteren Teil des Fallschachtes 2 in der Mittellängsebene des Ofens abzweigenden Abgaskanal 3 in zwei seitliche Fallschächte kleineren Querschnitts, die aber hinter der Backraumrückwand noch im horizontalen Querschnitt miteinander in Verbindung stehen, aufgeteilt, so daß die aufsteigenden Heizgase des Brenners den mittleren Abgaskanal 3 wirkungsvoll umspülen. Die leichte Schrägführung des über dem Brenner 5 angeordneten Mehretagiger gasbeheizter BackofenThe drawing, which speaks for itself, shows an oven block with four baking chambers arranged one above the other recognize, which the burner exhaust gases from the multi-tube burner 5 by two from Fig. 1 can be seen Openings in the back wall of the baking chamber flow in at the rear, while they flow in behind the oven doors arranged chute 2 are reunited. The heating gas riser shaft 1 behind the baking rooms is branched off by one of the lower part of the chute 2 in the central longitudinal plane of the furnace Exhaust duct 3 into two lateral chutes of smaller cross-section, but behind the back wall of the baking chamber are still in connection with each other in the horizontal cross-section, divided so that the The middle flue gas duct 3 is effectively flushed around the rising hot gases from the burner. The easy Inclined guidance of the multi-level gas-heated oven arranged above the burner 5

Einlaufendes des Abgaskanals 3 unterstützt noch die durch seine Beheizung von außen sich sowieso schon ergebende Zugbegünstigung. Die im Ofen abgekühlten Brennergase verlassen den Ofenblock durch den Abgasstutzen 4.The inlet end of the exhaust duct 3 still supports itself anyway through its heating from the outside resulting train preferential treatment. The burner gases cooled in the furnace leave the furnace block through the Exhaust nozzle 4.
Aus Sicherheitsgründen zwecks schneller Entfernung noch brennfähiger Restgase aus dem Feuerraum und auch zur Erleichterung des Anheizens des kalten Ofens sind die in Fig. 2 angedeuteten Sicherheits- und Anheizklappen 6 am Abgaskanal 3 angeordnet. Zweckmäßigerweise werden diese Klappen durch das Brenner-Ausschaltorgan beim Abschalten des Brenners selbsttätig geöffnet, damit sofort die Strömung durch die Backräume unterbrochen wird. Dagegen müssen sich die erwähnten Klappen 6 schließen, wenn der Brenner wieder eingeschaltet wird, falls nicht die Auskühlung des Ofens ein längeres Offenhalten bis zum Erreichen einer bestimmten Temperatur des Abgaskanals 3 verlangt. Für den letzteren Fall kann ein Bimetallschließorgan 6', z. B. in Form einer Spirale nach Fig. 4, vorgesehen werden, das die auch nach Einschalten des Brenners noch geöffnete Klappe 6 bei Erreichen der für die Zugerzeugung nötigen Temperatur des Abgaskanals 3 selbsttätig schließt.For safety reasons, for the purpose of faster removal of still flammable residual gases from the combustion chamber and also to make it easier to heat up the cold oven, the safety and security measures indicated in FIG Heating flaps 6 are arranged on the exhaust gas duct 3. These flaps are expediently activated by the burner shut-off device automatically opens when the burner is switched off, so that the flow immediately flows through the baking rooms is interrupted. In contrast, the mentioned flaps 6 must close when the The burner is switched on again, unless the furnace has cooled down by holding it open for a longer period of time required to reach a certain temperature of the exhaust gas duct 3. In the latter case, a Bimetallic closing element 6 ', e.g. B. in the form of a spiral according to FIG. 4, are provided, which also after Switching on the burner, still open flap 6, when the temperature required for generating the draft has been reached of the exhaust duct 3 closes automatically.
