The insert () is adapted to be fitted into an atomizer wheel. Each insert () has a longitudinal axis and comprises an inner end face (), an outer end face (), an external surface () and an internal surface () defining a channel () having a center axis (c) and extending between an inlet () at the inner end face () and an outlet () at the outer end face (). At least the inlet () is offset from the longitudinal axis such that the center axis of the channel () is offset from the longitudinal axis of the insert (). The insert () 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.

Insert for an atomizer wheel and atomizer wheel comprising a number of such inserts

The atomizer wheel includes a plurality of ejection apertures distributed over the circumference of an external wall, in which a plurality of inserts are arranged. The inserts each includes a bushing and a wear-resistant lining arranged in the bushing such that a contact surface of the lining abuts against an internal side of the bushing. Each insert is provided with a transition surface extending between an inner end face of the lining and the contact surface, and the transition surface includes at least one portion forming an angle with the contact surface, by which it is possible to direct the flow of the material to be atomized along the transition surface of the lining and farther down to the inner side of the external wall and thus avoid wear on the bushing.
