Abstract
Description
Die Erfindung betrifft eine Abgas- und Zuluftführung für einen von zumindest einem Brenner beheizten Brennraum mit einer zum Sammeln von Kondensat dienenden Wanne od. dgl. Kondensatsammler.The invention relates to an exhaust gas and supply air duct for a combustion chamber heated by at least one burner with a trough for collecting condensate Like. Condensate collector.
Aufgabe der Erfindung ist es, auf einfache Weise und ohne nennenswerten konstruktiven Aufwand für eine Kühlung der Kondensatwanne Sorge zu tragen.The object of the invention is simple and without any significant design effort for cooling to take care of the condensate pan.
Erfindungsgemäß ist ein Anteil der zum Brenner geführten Zuluft abgezweigt und zur Kühlung der Wanne zumindest bereichsweise entlang deren Boden geführt.According to the invention, a portion of the burner branched supply air and for cooling the tub led at least in regions along the bottom.
Diese Maßnahme erbringt - abgesehen vom Kühleffekt - den zusätzlichen Vorteil, daß ein zur Versorgung des Brenners fallweise nicht erforderlicher, überschüssiger Anteil der Zuluft nutzbringend verwertet wird. Ein solcher Zuluftüberschuß tritt beispielsweise dann auf, wenn dem Brennraum ein der Förderung der Abgase dienendes Gebläse zugeordnet ist. Wenn nämlich für Brennräume ohne Kondensat sammler bemessene Gebläse fallweise für mit solchen Sammlern ausgestattete Brennräume verwendet werden, ist das von einem solchen Serien-Gebläse geförderte Volumen bedingt durch die niedrigere Temperatur der Abgase höher als für den Frischluftbedarf des Brenners erforderlich ist. Dank der erfindungsgemäßen Lösung können also vorteilhafterweise Gebläse gleich hoher Kapazität (Serienerzeugnisse) für Brennräume mit oder ohne Kondensatsammler gleichermaßen mit ihrer vollen Kapazität nutzbringend verwendet werden.Apart from the cooling effect , this measure has the additional advantage that an excess portion of the supply air that is not necessary in some cases for supplying the burner is usefully utilized. Such a supply air excess occurs, for example, when a blower serving to convey the exhaust gases is assigned to the combustion chamber. If namely for combustion chambers without a condensate collector, blowers are used occasionally for combustion chambers equipped with such collectors, the volume conveyed by such a series fan is higher due to the lower temperature of the exhaust gases than is necessary for the fresh air requirement of the burner. Thanks to the solution according to the invention, fans of the same capacity (series products) can advantageously be used for combustion chambers with or without condensate collectors with their full capacity.
Zahlreiche weitere Erfindungsmerkmale werden der besseren Verständlichkeit wegen nachstehend an Hand der Zeichnung erläutert, die im schematischen Aufriß einen Brennraum mit erfindungsgemäßer Abgas- und Zuluftführung beispielsweise veranschaulicht.Numerous other features of the invention are the better understandability because of the following on hand the drawing explains the schematic elevation a combustion chamber with the exhaust gas and Supply air routing, for example, illustrated.
Oberhalb des von einem Brenner 1 beheizten, einen Primärwärmetauscher 2 enthaltenden Brennraumes 3 befindet sich ein oben von einer Abgassammelhaube 4 abgedeckter Kondensatsammler in Form einer Wanne 5, dessen Unterseite vom Boden 6 gebildet ist. Dieser Wannenboden 6 verläuft schräg und besitzt an seiner tiefstgelegenen Stelle einen Kondensatabfluß 7.Above the heated by a burner 1, a primary heat exchanger 2 containing the combustion space 3 is a covered up by a waste gas collecting hood 4 condensate collector in the form of a tray 5, the underside of which is formed from the bottom. 6 This trough bottom 6 runs obliquely and has a condensate drain 7 at its lowest point.
Entlang der Unterseite dieses Bodens 6 verläuft eine Führung 8 für einen durch ihren Querschnitt bestimmbaren und bemeßbaren Anteil der dem Brenner 1 über eine Zuluftführung 9 insgesamt zugeführten Zuluft (Frischluft).A guide 8 runs along the underside of this base 6 for a portion of the supply air (fresh air) which is supplied to the burner 1 via a supply air guide 9 and can be determined and measured by its cross section.
In der Abgassammelhaube 4 ist gemäß dem linken Teil der Zeichnung ein Kondensationswärmetauscher 10 angeordnet, der der Verwertung der Abgaswärme, z.B. dem Vorwärmen eines im Primärwärmetauscher 2 zu erhitzenden Brauch und/oder Heizungswassers, dient.In the exhaust gas collecting hood 4 , a condensation heat exchanger 10 is arranged according to the left part of the drawing, which is used to utilize the exhaust gas heat, for example the preheating of a custom and / or heating water to be heated in the primary heat exchanger 2 .
In der Abgassammelhaube 4 ist ferner ein Gebläse 11 mit einem Antrieb 12 angeordnet, das die sich in der Haube 4 sammelnden Abgase einer Abgasleitung 13 zuführt, die ihrerseits von der der Zuluftzufuhr dienenden Führung 9 ummantelt ist. In the exhaust gas hood 4 there is also a blower 11 with a drive 12 which feeds the exhaust gases collecting in the hood 4 to an exhaust gas line 13 , which in turn is encased by the guide 9 which serves to supply air.
Zwischen dem Kondensationswärmetauscher 10 und dem an den Einlaß der Abgasleitung 13 angeschlossenen Gebläse 11 ist in der Abgassammelhaube 4 eine Aus nehmung 14 gebildet, durch die der von dem zum Brenner 1 geführten Hauptstrom abgezweigte Anteil der Zuluft außerhalb der Sammelhaube 4 aufwärts strömend - gewissermaßen im Kurzschluß - zum Gebläse 11 gelangt.Between the condensation heat exchanger 10 and the fan 11 connected to the inlet of the exhaust gas line 13 , a recess 14 is formed in the exhaust gas hood 4 , through which the portion of the supply air diverted from the main stream leading to the burner 1 flows upward outside the collecting hood 4 - to a certain extent in a short circuit - Get to the blower 11 .
Der zur Kühlung des Kondensatsammlers dienende Zuluftanteil könnte im Rahmen der Erfindung aber auch an anderer Stelle der Abgassammelhaube 4 abgeleitet werden.The supply air portion used to cool the condensate collector could, however, also be derived from the exhaust gas hood 4 elsewhere within the scope of the invention.
