R&V oil burners

The oil burner consists of a spiral atomizer head for the oil and two swirl chambers, the rotating air in the first chamber supports the initial swirl of the oil film. The second swirl chamber rotates the air in the opposite direction. This produces the effect of two violently rotating "air knives", which reduce the oil film to very fine particles.

The combustion air passes through the annulus formed by the deflector and the burner throat, parallel to the centerline of the burner. The effective oil pressure at the burner on full load will be about 300-500 kPa. The advantages of the low-pressure oil system are self-evident. The atomization (by using low-pressure air) brings substantial savings in operating costs when compared to pressure atomization or steam atomization. The overall design is such that, if fuel changes are required after the installation of a single fuel oil burner, it is a simple matter to add a gas burner to the oil burner (or vice versa), without any change to the burner throat or windbox.
