Heat exchanger with burner, provided with a longitudinal combustion chamber (1) bounded on both sides by a first (2) and a second (3) wall. The combustion chamber (1) has an entrance opening (4) and an exit opening (5). A fuel and an oxidant are supplied to the entrance opening (4) of the combustion chamber (1). A slit-shaped element (7) is provided for forming a first slit-shaped passage (8) having an outlet with the first wall (2) and for forming a second slit-shaped (9) passage having an outlet with the second wall (3). Each slit-shaped passage (8,9) has a length which is a part of the height of the wall concerned. Through the first (8) and the second (9) slit-shaped passages the mixed flow enters the combustion chamber (1) as first partial flow (10) and second partial flow (11), respectively. The first partial flow (10) and the second partial flow (11) are ignited. The distance between the first (2) and the second (3) wall decreases toward the exit opening of the combustion chamber (1) for directing the first (10) and the second (11) ignited partial flows to each other. A heat exchanger (13) unit with a chamber (14) is contiguous to the exit opening (5) of the combustion chamber (1) and has hollow walls (15,15') for containing cooling agent surrounding the chamber (14). The walls (2,3) of the combustion chamber (1) are an integrated part of the walls (15,15') of the heat exchanger unit (13). <IMAGE> |
