REFRACTORY MATERIAL REMOVAL SYSTEM AND METHOD

摘要

Apparatus for removing refractory lining the inside of a cylindrical structure comprising a traveler received within the structure and movable along its length, the traveler including a securing means that secures the traveler within the structure in a manner that allows the traveler to be intentionally moved, a rotatable nozzle assembly being connected to the traveler, the nozzle assembly comprising one or more nozzle lines each terminating in a nozzle head that rotates, the nozzle assembly being configured in a manner that each nozzle head is suitably spaced from the refractory to be able to deliver a jet of fluid under pressure to the refractory, a nozzle rotation means for rotating the nozzle assembly, and a conduit means in fluid communication with the nozzle assembly suitable for delivering a flow of fluid to the nozzle assembly under sufficient pressure to cut the refractory material lining the structure. A method employing the apparatus for removing refractory.
