COAL ROPE DISTRIBUTOR WITH REPLACEABLE WEAR COMPONENTS

摘要

A head assembly for a pulverized coal nozzle includes removeable wear-resistant inserts having vanes. The vanes may be flat or curved to direct a stream of air and pulverized solid fuel particles from the inlet port toward the outlet port. The curved vanes curve in two dimensions to evenly distribute the stream of air and pulverized solid fuel away from the outer surfaces reducing wear and corrosion. The pipe elbow has a removable cover that allows for easy access. The vanes are attached to a wear-resistant replaceable liner thus allowing them to be easily removed and replaced. The wear-resistant liner may be made from several parts for ease of removal and replacement.

1. 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 extending circumferentially about the internal cavity and wall 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.
