Abstract
The insert (20) is adapted to be fitted into an atomizer wheel. Each insert (20) has a longitudinal axis and comprises an inner end face (21), an outer end face (22), an external surface (23) and an internal surface (24) defining a channel (35) having a center axis (c) and extending between an inlet (25) at the inner end face (21) and an outlet (26) at the outer end face (22). At least the inlet (25) is offset from the longitudinal axis such that the center axis of the channel (35) is offset from the longitudinal axis of the insert (20). The insert (20) is adapted to be utilized in an atomizer wheel for a spray dryer for atomizing slurries of abrasive material, for instance for spray drying absorption for flue gas cleaning.
Claims24
An atomizer wheel for a spray dryer for atomizing slurries of abrasive material, comprising:
- a substantially cylindrical external wall defining an annular chamber and a radial direction of the atomizer wheel,
- a plurality of ejection apertures distributed over the circumference of said external wall, and
- a plurality of inserts arranged in said ejection apertures, each insert spanning at least the entire width of the external wall of the atomizer wheel and having a longitudinal axis and comprising:
- an inner end face configured to be exposed to an annular chamber of the atomizer wheel, the insert being configured for the inner end face to extend into the annular chamber;
- an outer end face configured to be exposed to an outside of the atomizer wheel;
- an external surface;
- and
- an internal surface defining only a single substantially straight channel having a centre axis and extending between an inlet at the inner end face and an outlet at the outer end face, the insert being configured for said inlet to be positioned in the annular chamber, and an outlet at the outer end face, wherein at least said inlet is offset from the longitudinal axis such that the centre axis of the channel is substantially parallel to and offset from the longitudinal axis of the insert, whereby the insert is provided with an enlarged portion at the inner end face and the inlet containing a larger amount of material between the external surface and the internal surface in one segment of the insert than in an opposite segment relative to the centre axis.
