Abstract

Der Heizungskessel ist für die Verbrennung flüssiger oder gas­ förmiger Brennstoffe bestimmt und besteht aus einem wasserfüh­ renden Gehäuse (1), in dem ein Feuerraum (2) mit zum Gasabzugs­ stutzen (3) führender Gasabzugsstrecke (S) und vor dem Feuer­ raum (2) das Gehäuse (4) eines Gebläsebrenners (5) angeordnet ist, das über einen Abgasrückführkanal mit dem Abzugsbereich des Kessels in Verbindung steht. Um für eine teilweise Abgas­ rückführung an einem solchen Kessel sorgen zu können und dafür keine äußere Abgasrückführleitung anordnen zu müssen, ist zwi­ schen dem gegenüber der Luftansaugseite befindlichen Unter­ druckseite (6) der Läuferkammer (7) des Gebläsegehäuses (4) und dem brennerseitigen Abschlußbereich (8) des Feuerraumes (2) eine den Abgasrückführkanal bildende Überströmöffnung (9) ange­ ordnet. Diese Abgasüberströmöffnung (9) verbindet die Läufer­ kammer (7) mit dem Endbereich (S′) der Gasabzugsstrecke (S). Das Läuferrad (12) des Gebläses ist dabei überströmkanalseitig saugwirksam ausgebildet. The boiler is for burning liquid or gas shaped fuels and consists of a water Renden housing (1) in which a combustion chamber (2) with the gas exhaust Nozzle (3) leading gas discharge line (S) and in front of the fire space (2) the housing (4) of a forced draft burner (5) is arranged is that via an exhaust gas recirculation duct with the exhaust area of the boiler is connected. In order for a partial exhaust feedback on such a boiler and to be able to no external exhaust gas recirculation line has to be arranged between the lower part opposite the air intake side pressure side (6) of the rotor chamber (7) of the blower housing (4) and the burner end area (8) of the combustion chamber (2) an overflow opening (9) forming the exhaust gas recirculation channel arranges. This exhaust gas overflow opening (9) connects the rotor chamber (7) with the end region (S ') of the gas discharge section (S). The fan wheel (12) of the fan is on the overflow channel side trained effective suction.
