Abstract (en)
[origin: EP1482245A1] Device for regulating the gas/air ratio for a pre-mixing combustion device comprises a pneumatic regulator holding constant the ratio between the pressure in a gas line (1) and the pressure in an air line (2), a mixing device (4) arranged downstream of the regulator, and a fan (5) with speed control for conveying the mixture from the mixing chamber to the combustion device. The mixing device comprises a mixing chamber (7) that widens in the manner of a venturi nozzle from its inlet opening in the flow direction, a nozzle (8) connected to the air line and protruding into the inlet opening, an annular gap (10) connected to the gas line and formed between the edge (9) of the inlet opening and the nozzle, and a cone (11) arranged in the air line and adjusted according to the signal of a sensor in the axial direction relative to the nozzle.
