Zusammenfassung:	A nozzle for introducing pressurized fluids into an industrial vessel is releasably attachable to and detachable from a mounting member securedly attached to an exterior surface of the vessel. The mounting member is attached, via extension piping, to a source of pressurized gas, such as the exhaust valve of an air cannon. Both the nozzle and the mounting member include respective mating collars which engage each other in a twist lock manner. Additional securing members are provided to securely retain the nozzle and mounting member in twist lock engagement. Removal of the nozzle is performed by releasing the securing members, twisting the nozzle from inside of the vessel to unlock it from the mounting member, and uncoupling the nozzle from the mounting member. Installation of a replacement nozzle is performed by performing the foregoing steps in the reverse order. For high temperature applications, the removal of existing refractory material may be necessary prior to removal of a worn nozzle, and new refractory material may be applied to the interior surface of the vessel following attachment of the replacement nozzle.
