The oven has a heat-insulated water storage tank (2) located above the oven chamber, and linked to a heat exchanger. Effluent hot air is drawn through the chimney by a ventilator. The hot water boiler encompasses a vapor condenser, a heat exchanger linked to the heater arrangement, and a smoke gas washer. The storage tank (2) incorporates a further heat exchanger (19) which is linked with an absorption refrigerator (32) which preferably forms an integral part of the oven and operates either continually or intermittently. Preferred Feature: The boiler-absorber (26) is linked to the heat exchanger inlet pipe (19).

Description

Die Erfindung betrifft einen Backofen mit Energierückgewinnung, der vorzugsweise mit einem öl- oder gasbetriebenen Brenner betrieben wird.The invention relates to an oven Energy recovery, preferably with a oil or gas powered burner is operated.

Bekannt sind zur Energierückgewinnung bei Backöfen die Verwendung von Wärmetauschern, mit deren Hilfe dem Rauchgas sowie den Backschwaden die Abwärme entzogen wird. So beispielsweise aus der DE 195 39 858 A1 wird zu einem geringen Teil zur Vorwärmung der Verbrennungsluft, zum anderen - das ist der weitaus größere Teil - zur Erwärmung von Brauchwasser für Heizungs- und Wascheinrichtungen bzw. zur Dampferzeugung genutzt.Are known for energy recovery in ovens Use of heat exchangers with the help of which The waste heat is extracted from the flue gas and the baking steam becomes. For example, from DE 195 39 858 A1 a small part for preheating the combustion air, on the other hand - that is the far larger part - for Heating of domestic water for heating and Washing facilities or used to generate steam.

Ein Nachteil dieser Lösungen besteht darin, daß gerade in der wärmeren Jahreszeit weniger Brauchwasser benötigt wird. Dadurch entsteht ein Überschuß an zurückgewonnener Wärmeenergie.A disadvantage of these solutions is that straight less hot water is required in the warmer season becomes. This creates an excess of recovered Thermal energy.

Die Aufgabe wird erfindungsgemaß durch die Merkmale des kennzeichnenden Teils des Hauptanspruches gelöst. Besondere Ausführungsarten sind den übrigen Unteransprüchen zu entnehmen.The object is achieved by the features of characterizing part of the main claim solved. The other are special designs See subclaims.

Der Wärmetauscher 18 umgibt den Rauchgaskanal 16 und weist im unteren Bereich einen Einlaß 19 und im oberen Bereich einen Austritt 20 auf. Beide sind mit dem Speicherboiler 2 verbunden. Im Speicherboiler 2 sind jeweils ein Wärmetauscher 3 für Brauchwasser und ein Wärmetauscher 4 für die Heizung angeordnet.The heat exchanger 18 surrounds the flue gas duct 16 and has an inlet 19 in the lower region and an outlet 20 in the upper region. Both are connected to the storage boiler 2 . A heat exchanger 3 for domestic water and a heat exchanger 4 for heating are arranged in the storage boiler 2 .

Der Schwadenabzug 5 der Backetagen steht mit dem im Speicherboiler 2 angeordneten Schwadenkondensator in Verbindung. Der Schwadenabzugsaustritt 6 ist mit dem Rauchgaswäscher 25 verbunden.The steam draw 5 of the baking floors is connected to the steam condenser arranged in the storage boiler 2 . The steam outlet 6 is connected to the flue gas scrubber 25 .

Unterhalb des Wärmetauschers 18 ist eine Luftvorwärmung 17 in Form eines Doppelmanteltauschers angeordnet, in der die Verbrennungsluft für den Brenner vorgewärmt wird. An air preheater 17 in the form of a double jacket exchanger is arranged below the heat exchanger 18 , in which the combustion air for the burner is preheated.

Der Rauchgaswäscher 25 ist mit dem Rauchgasabzug 16 der Brennkammer verbunden. Im oberen Bereich weist dieser einen Kondensataustritt 11 auf, der über die Pumpe 13 und die Leitung 14 mit dem Kondensatbehälter 12 verbunden ist. Die Leitung 14 und der Kondensataustritt 11 sind mit einer innerhalb des Speicherboilers 2 liegenden Rohrschlange verbunden. Der Kondensatbehälter 12 ist mit dem Kondensatabfluß 15 verbunden.The flue gas scrubber 25 is connected to the flue gas outlet 16 of the combustion chamber. In the upper area, this has a condensate outlet 11 , which is connected to the condensate container 12 via the pump 13 and the line 14 . The line 14 and the condensate outlet 11 are connected to a pipe coil lying inside the storage boiler 2 . The condensate container 12 is connected to the condensate drain 15 .

Im Rauchgaswäscher 25 wird das heruntergekühlte Rauchgas gereinigt, neutralisiert und weiter abgekühlt. Der Ausgang des Rauchgaswäschers 25 ist mit dem Abluftkanal 8 verbunden. Im Abluftkanal 8 ist ein Ventilator 7 zur Erzeugung eines Unterdruckes angeordnet. Am Abluftkanal 8 ist vor dem Ventilator 7 ein Bypasskanal 9 mit einer verschließbaren Klappe und ein Nebenlufteintritt 10 angeordnet. Dies dient als Überhitzungsschutz für den Speicherboiler 2.The cooled down flue gas is cleaned, neutralized and further cooled in the flue gas scrubber 25 . The outlet of the flue gas scrubber 25 is connected to the exhaust air duct 8 . A fan 7 for generating a negative pressure is arranged in the exhaust air duct 8 . A bypass duct 9 with a closable flap and a secondary air inlet 10 are arranged on the exhaust duct 8 in front of the fan 7 . This serves as protection against overheating for the storage boiler 2 .

Neben dem Etagenbackofen ist ein Gärschrank angeordnet. Die für die Gärung notwendige Warmluft wird aus der Restwärmeenergie der Abluft gewonnen. Der Abluftkanal 8 im unteren Bereich ist dazu als Doppelrohrwärmetauscher 23 ausgelegt. Der Luftaustritt 22 ist über einen Ventilator mit dem Gärbereich verbunden. Über den Lufteintritt 24 wird die zu erwärmende Luft angesaugt.A proofing cabinet is located next to the deck oven. The warm air required for fermentation is obtained from the residual heat energy in the exhaust air. The exhaust air duct 8 in the lower area is designed as a double-tube heat exchanger 23 .
