COAL ROPE DISTRIBUTOR WITH REPLACEABLE WEAR COMPONENTS

摘要

A head assembly 52, 152 for a pulverized coal nozzle includes removeable wear-resistant inserts having vanes 54, 151, 153. The vanes 54, 151, 153 may be flat or curved to direct a stream of air and pulverized solid fuel particles from the inlet port 60, 160 toward the outlet port 62, 162. The curved vanes 151, 153 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 70, 170 that allows for easy access. The vanes are attached to a wear-resistant replaceable liner 185 thus allowing them to be easily removed and replaced. The wear-resistant liner 185 may be made from several parts 187, 189 for ease of removal and replacement.
