<p>The boiler has a heat exchanger (7) with a housing (9) provided in vertically held tube bundles (10-12) for guidance of exhaust gases from a combustion chamber (2). A flow chamber (4) is attached at a return fuel line (6) of a heat transfer medium and provided between the combustion chamber and a mantle (3) that partially encloses the combustion chamber. The flow chamber stays in flow-connection with the housing of the heat exchanger over passage openings (18) such that the housing upwardly overlaps with the combustion chamber, and tubes of the tube bundles end in the combustion chamber.</p> |
