Mixing device for e.g. oil burner, has face plate including central flow opening arranged coaxial to fuel nozzle for combustion air, where inner combustion air stream surrounds fuel nozzle via flow opening

摘要

The device has a combustion air channel attached at a blower, and opening out into an upstream of face plate (4) to a housing (7). The plate includes a flow opening (5) provided in an orifice area of the combustion air channel. The plate includes a central flow opening arranged coaxial to a fuel nozzle (3) for a combustion air, where inner combustion air stream surrounds the nozzle via the opening. Outer combustion air stream surrounds the inner combustion air stream close to a fuel stream via the opening, where the inner and outer air streams at a distributor mechanism (8) are divided.
