摘要： A method of treating refractory-lined equipment includes accessing an interior of the refractory-lined equipment with an equipment repair apparatus, wherein the equipment repair apparatus includes a robotic arm and one or more end effectors coupled to an end of the robotic arm, inspecting refractory material that lines an inner wall of the refractory-lined equipment with a first end effector coupled to the end of the robotic arm, removing damaged refractory material from the inner wall with a second end effector coupled to the end of the robotic arm, removing one or more anchors from the inner wall with a third end effector coupled to the end of the robotic arm, and installing new refractory material on the inner wall with a fourth end effector coupled to the end of the robotic arm.

摘要： A refractory-lined equipment includes a vessel defining an interior at least partially lined with a refractory material, and a nozzle assembly coupled to the vessel and extending into the interior. The nozzle assembly includes an outer sleeve fixed to the sidewall and extending through an aperture defined in the sidewall, the outer sleeve defining a central passageway, and a nozzle cartridge assembly positionable within the central passageway and including an inner sleeve, a refractory lining disposed about the inner sleeve, and a nozzle positioned within the inner sleeve. The nozzle cartridge assembly is removably coupled to the outer sleeve external to the vessel.

摘要： A system for preparing a dry process material includes a sealed container that holds and seals the dry process material therein and prevents airborne dust or particles from the dry process material from escaping the sealed container. Sealed processing equipment receives the dry process material from the sealed container and prevents the airborne dust or particles from escaping the sealed processing equipment. A sealed connection sealingly couples the sealed container to the sealed processing equipment and prevents the airborne dust or particles from escaping while transferring the dry process material. A sealed transfer conduit is sealingly coupled to and extends from the sealed processing equipment.
