ABSTRACT:
A double-ring ceramic ferrule member insertable into a fire tube of a sulfur plant boiler or cooler, the invention comprises an article of manufacture capable of reducing damage caused by high temperature gas flow through a fire tube, thereby to protect the fire tube and the tube sheet through which the fire tube extends. The present ferrule member provides improved anchoring capability and increased resistance to fire tube erosion.
