Die Neuerung betrifft einen Heizkessel nach dem Oberbegriff des Schutzanspruches 1.The innovation concerns a heating boiler according to the generic term of claim 1.
Bei Brennwertkesseln sind üblicherweise der Brennrraum und der Brennwertwärmetauscher aus demselben Werkstoff gefertigt. Der gesamte Kessel besteht dabei aus einem hochwertigen Material, obwohl dieses nur in einem Teilbereich des Kessels unbedingt erforderlich ist. Es wurde auch schon vorgeschlagen, einen separaten Brennwertwärmetauscher aus säurebeständigem Material in den Kessel aus üblichem Kesselwerkstoff einzufügen und ihn wasserseitig anzuflanschen, !n jeder Zone des Kessels ist dadurch das geeignete Material vorhanden.In condensing boilers, the combustion chamber and the condensing heat exchanger are usually made of the same material. The entire boiler is made of a high-quality material, although this is only absolutely necessary in one part of the boiler. It has also been suggested that a separate condensing heat exchanger made of acid-resistant material be inserted into the boiler made of standard boiler material and flanged to the water side, so that the appropriate material is available in every zone of the boiler.
Der Neuerung liegt die Aufgabe zugrunde, einen Gliederheizkessel aus gußeisernen Kesselgüedern so zu gestalten, daß das Einflanschen eines separaten Brennwertwärmetauschers aus hochresistentem Material möglich ist.The innovation is based on the task of designing a sectional boiler made of cast iron boiler parts in such a way that a separate condensing heat exchanger made of highly resistant material can be flanged in.
Der neuerungsgemäße Heizkessel ist dadurch gekennzeichnet, daß er als Gliederheizkessei aus zwei schalenförmigen Kesselgliedern ausgebildet ist, welche einen horizontalen Brennraum und einen daran anschließenden Heizgasschacht mit einem integrierten Kompaktwärmetauscher umgeben.The heating boiler according to the innovation is characterized in that it is designed as a sectional heating boiler made up of two shell-shaped boiler sections, which surround a horizontal combustion chamber and an adjoining heating gas shaft with an integrated compact heat exchanger.
Die beiden schalenförmigen Kesselglieder können im Gießverfahren sehr einfach hergestellt werden. Auch der Zusammenbau der beiden schalenförmigen Kesselglieder und des Kompaktwärmetauschers ist problemlos durchzuführen.The two shell-shaped boiler sections can be manufactured very easily using the casting process. The two shell-shaped boiler sections and the compact heat exchanger can also be assembled without any problems.
10.12.1996 /G 135310.12.1996 /G 1353
Es empfiehlt sich, den Heizgasschacht mit dem integrierten Kompaktwärmetauscher vom Ende des Brennraumes aus abwärts zu führen. Dabei sollte der Kompaktwärmetauscher direkt hinter dem Austritt des Brennraumes angeordnet sein und ihm eine mit Strahlungsrippen besetzte Übergangsheizfläche vorgeschaltet sein. Letztere kühlt das Heizgas auf ein für die Dichtungen ertragliches Maß ab.It is recommended that the heating gas shaft with the integrated compact heat exchanger be led downwards from the end of the combustion chamber. The compact heat exchanger should be positioned directly behind the combustion chamber outlet and a transition heating surface with radiant fins should be installed in front of it. The latter cools the heating gas to a level that is acceptable for the seals.
Da im Kompaktwärmetauscher eine Abkühlung der Heizgase bis unter den Taupunkt erfolgt, können die nachgeschalteten Abgaswege aus Kunststoff bestehen und als Gestell für die Kesselglieder dienen. Die benötigte Neutraiisationseinrichtung kann untergeschoben werden.Since the heating gases are cooled to below the dew point in the compact heat exchanger, the downstream exhaust gas paths can be made of plastic and serve as a frame for the boiler sections. The required neutralization device can be pushed underneath.
Die Zeichnung stellt ein Ausführungsbeispiel der Neuerung dar. Es zeigt:

Der Heizkessel besteht aus zwei schalenförmigen Kesselgliedern 1, die einen Brennraum 2 und einen Heizgasschacht 3 umgeben. Im Heizgasschacht 3 sitzt ein Kompaktwärmetauscher 4 aus einem hochresistenten Material. Er ist wasserseitig mit den Kesselgliedern verbunden. Vom Brennraum 2 her ist ihm eine mit Strahlungsrippen besetzte Übergangsheizfläche 5 vorgeschaltet.The boiler consists of two shell-shaped boiler sections 1, which surround a combustion chamber 2 and a heating gas shaft 3. A compact heat exchanger 4 made of a highly resistant material is located in the heating gas shaft 3. It is connected to the boiler sections on the water side. A transition heating surface 5 with radiant fins is connected upstream of it from the combustion chamber 2.
Die Heizgase strömen aus dem Brennraum 2 an der Übergangsheizfläche 5 vorbei durch den Kompaktwärmetauscher 4, in welchem sie bis unter den Taupunkt abgekühlt werden. Aus dem Sammelraum 6 gelangen sie dann durch den Abgasstutzen 7 und ein Abgasrohr zum Schornstein. Das kühle Rücklaufwasser strömt durch den Rücklaufanschluß 8 zunächst in den Kompaktwärmetauscher 4. Es dient hier einem starken Abkühlen der Heizgase im Sinne eines Brennwerteffektes. Danach werden auch die Kesselglieder 1 als Hochtemperaturbereich des Kessels durchströmt. Das heiße Wasser verläßt den Kessel durch den Vorlaufanschluß 9.The heating gases flow from the combustion chamber 2 past the transition heating surface 5 through the compact heat exchanger 4, in which they are cooled to below the dew point. From the collection chamber 6 they then pass through the exhaust gas nozzle 7 and an exhaust pipe to the chimney. The cool return water flows through the return connection 8 first into the compact heat exchanger 4. It serves to cool the heating gases significantly in the sense of a calorific value effect. The water then flows through the boiler sections 1 as the high-temperature area of the boiler. The hot water leaves the boiler through the flow connection 9.
10.12.1996. G 135310.12.1996. G1353
Da die Heizgase im Kompaktwärmetauscher 4 jedenfalls bis unter den Taupunkt abgekühlt werden, können die nachgeschalteten Abgaswege, nämlich der Sammelraum 6 und der Abgasstutzen 7, aus Kunststoff bestehen, der gegen das entstehende saure Kondenswasser resistent ist. Dieses Wasser gelangt in eine untergeschobene Wanne 10, die als Neutralisationseinrichtung gestaltet ist. Durch den Abiauf 11 fließt es in die Kanalisation. Since the heating gases in the compact heat exchanger 4 are cooled to below the dew point, the downstream exhaust gas paths, namely the collection chamber 6 and the exhaust gas nozzle 7, can be made of plastic that is resistant to the acidic condensate that is produced. This water flows into a tray 10 that is pushed underneath and is designed as a neutralization device. It flows into the sewer system through the drain 11.
