摘要

Burner for a gas boiler or the like comprising one elongate burner tube (1) which is provided with a zone extending in the longitudinal direction and having burner openings (2), and which is closed at both ends by an end wall (3,4). The burner tube (1) contains a venturi tube (5), whose inlet mouth (6) projects through the end wall (3) while the outlet end (8) of the venturi tube lies some distance from the other end wall (4). Inside the burner tube a partition (9) has been arranged which extends in the axial direction at least from the outlet end (8) of the venturi tube to the burner tube end wall (4) facing it. The partition (9) is substantially parallel to and at a distance from the wall of the tube and in the region remote of the burner openings (2) provided with an elongate gap (10). The partition (9) is also provided with a deflector (11) which diverts the mixture flowing out of the venturi tube in the direction of the gap (10) in the partition, the mixture flowing further through the passages (12) between the partition (9) and the wall of the burner tube to the burner openings (2).
