Abstract
A novel blaster nozzle 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 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 connected to the nozzle head and a connection tube extends from the flange member for connecting the blaster nozzle to an air cannon.

A method of installing a blaster nozzle in a refractory lined enclosure housing so that the blaster nozzle may assist in the pneumatic removal of cloggings and/or cakings during the transport of particulate matter through the enclosure housing, the method comprising:
- (a) providing, outside an outer shell of the enclosure housing, a blaster nozzle, the blaster nozzle comprising a nozzle head, a flange member and a connection tube, the flange member being connected to the nozzle head, the connection tube extending from the flange member for connecting the blaster nozzle to an air cannon, the nozzle head comprising a refractory concrete having about 4-20% by volume metal fibers therein, the nozzle head having an inner surface which defines a passageway extending from adjacent the flange member for conduction of, and contact with, high-pressure air, the nozzle head having an orifice at a distal end of the passageway where high-pressure air is expellable from the blaster nozzle, the enclosure housing, including the outer shell thereof, having a hole sized to accommodate the blaster nozzle;
- (b) from outside the outer shell and through the hole in the outer shell, installing the blaster nozzle into the hole;
- and
- (c) attaching the flange member to the outer shell.
