Coal rope distributor with replaceable wear components

A head assembly for a nozzle, the head assembly comprising:

• a lower casing having an opening;
• a removable cover adapted to attach to the lower casing to cover the opening and form an elbow defining an internal cavity and having an input port and output port;
• a wear-resistant casing liner being tubular and disposed within the internal cavity to form a tubular inner wall extending circumferentially about the internal cavity and fluidly coupling the inlet port and the outlet port, the wear-resistant casing liner being insertable into and replaceable through the opening of the lower casing;
• and
• at least one wear-resistant, replaceable curved vane disposed within the internal cavity for directing a portion of a stream of fluidized particles from the inlet port to the outlet port to reduce contact with the wear-resistant casing liner, the at least one wear-resistant replaceable curved vane having a curved surface with a lengthwise radius of curvature, extending from a leading edge near the inlet port to a trailing edge near the outlet port, and a sideways radius of curvature.
