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.

A seal member for sealing a conveyor belt is a monolithic homogeneous piece of material having opposite first and second halves and comprises first and second primary seals and first and second secondary seals. The first secondary seal is resiliently movable relative to the first primary seal. The second secondary seal is resiliently movable relative to the second primary seal. The first primary seal and the first secondary seal are part of the first half of the seal member. The second primary seal and the second secondary seal are part of the second half of the seal member. When the seals on one of the first and second halves of the seal member become excessively worn, the seal member can be flipped so that the seals on the other half of the seal member can be utilized.
