Remote inspection, removal, and installation of refractory

A method of treating refractory-lined equipment, comprising:

• accessing an interior of the refractory-lined equipment with an equipment repair apparatus, wherein the equipment repair apparatus includes a main body supported by a chassis and a lifting mechanism for selectively adjusting a height of the main body relative to the chassis, one or more wheels coupled to the chassis, a robotic arm extending from the main body and an actuation device or drive cables for articulating the 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;
• installing new refractory material on the inner wall with a fourth end effector coupled to the end of the robotic arm;
• adjusting the height of the main body relative to the chassis with the lifting mechanism during one or more of the inspecting refractory material, removing damaged refractory material, removing one or more anchors, and installing new refractory material;
• and
• articulating the robotic arm with the actuation device or drive cables during one or more of the inspecting refractory material, removing damaged refractory material, removing one or more anchors, and installing new refractory material.
