Abstract
A head assemblyfor a pulverized coal nozzle includes removeable wear-resistant inserts having vanes. The vanesmay be flat or curved to direct a stream of air and pulverized solid fuel particles from the inlet porttoward the outlet port. The curved vanescurve 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 coverthat allows for easy access. The vanes are attached to a wear-resistant replaceable linerthus allowing them to be easily removed and replaced. The wear-resistant linermay be made from several partsfor ease of removal and replacement.
