Dabei werden die von den Kesselgliedern gebildeten Wasserkanäle und -taschen zwischen dem Kesselrücklauf und dem Kesselvorlauf durchströmt. Einerseits können die Gliederheizkessel einen unteren Kesselrücklauf und einen oben angeordneten Kesselvorlauf, vorzugsweise in der jeweiligen Nabe, besitzen. Andererseits ist auch eine gemeinsame Anordnung der beiden Anschlüsse in der oberen Nabe möglich. Die Heizgase strömen vom Brennraum über nachgeschaltete Heizgaszüge zu einem Abgasstutzen.Such sectional heating boilers consist of several integrally cast boiler sections, which are arranged one behind the other, connected on the water side by hubs and are in contact with each other on the hot gas side with the usual sealing zones.

On the one hand, the sectional boiler can be one lower boiler return and an upper boiler feed, preferably in of the respective hub. On the other hand, there is also a common arrangement of the two Connections in the upper hub possible. The heating gases flow over from the combustion chamber downstream heating gas flues to an exhaust pipe.
Bei allen bisherigen Kesseln dieser Art sind Kesselglieder in Reihe hintereinander angeordnet. Es gibt ein ringförmiges Vorderglied mit einer Brennraumtür, je nach Leistungsgröße ein oder mehrere ähnlich gestaltete Mittelglieder sowie ein Hinterglied. Dabei erstreckt sich der Brennraum durch Vorder- und Mittelglieder bis zum Hinterglied, welches mit seiner schalenförmigen Gestaltung den Boden des Brennraumes bildet. Alle Kesselglieder besitzen bei diesen Ausführungsformen ähnliche äußere Abmessungen, weil sie über den gesamten Kesselquerschnitt Teile von Brennraum, Heizgaszügen und Wasserraum bilden. Weiterhin sind auch Kessel für niedrige Leistungsbereiche bekannt, die aus nur zwei oder gar nur einem Kesselglied bestehen, etwa nach der DE 297 21 898 U1.In all previous boilers of this type, boiler sections are arranged in series one behind the other. There is an annular front link with a combustion chamber door, depending on the size of the power one or more similarly designed middle links and a rear link. It extends the combustion chamber through the front and middle limbs to the rear limb, which with its bowl-shaped design forms the bottom of the combustion chamber. All boiler sections have similar external dimensions in these embodiments because they cover the whole Boiler cross section forming parts of the combustion chamber, heating gas flues and water chamber. Furthermore, boilers for low power ranges are known, which consist of only two or there is even only one boiler section, for example according to DE 297 21 898 U1.
