ABSTRACT:
A novel blaster nozzle (10) used for assisting in the pneumatic removal of cloggings and cakings during the transport of particulate matter through an enclosure housing is set such that it can be removed and replaced from outside the enclosure housing. The blaster nozzle includes a nozzle head (12) having an orifice for the conduction of high-pressure fluid, wherein the nozzle head is composed of a refractory concrete having from about 4-20% by volume metal fibers therein. The blaster nozzle also includes a flange member (14) connected to the nozzle head and a connection tube (18) extends from the flange member for connecting the blaster nozzle to an air cannon.
