An insulated structure including a backing surface, a bar coupled to and extending generally parallel to the backing surface, and a plurality of insulating blankets coupled to the bar. The insulated structure further includes a clip coupled to the bar, the clip being attachable to the bar at any of a plurality of locations along the length of the bar to compress at least one of the blankets.

An insulated structure, typically a drum, can initially have an outer uninsulated wall of heat conductive material. The outer wall, such as the outer cylindrical wall of a drum, may then be insulated with insulation supplied as panels. Each panel covers a part of the surface, e.g., extends part way around a portion of the circumference of a drum. Each panel connects, end-to-end, to at least one other insulation panel. Adjacent panels are advantageously joined end-to-end by adjustable joining means. Each panel has an outer metal sheet, such as of galvanized steel. This sheet has an inner layer of ceramic fiber insulation bonded to it. In addition to being attached to each other, panels may also be secured to the wall.

A refractory lined duct is provided having sheet metal tube lined with a ceramic fiber matrix bonded with binder material forming a tubular refractory liner of predetermined thickness and thermal characteristics. This duct has the refractory liner held in fixed, retained relationship with the tube solely by frictional forces and adhesive bonding by the binder material. A method for making of this duct is provided and includes the steps of vacuum-forming of an elongated refractory sleeve or tube from a slurry of ceramic fibers and binder materials onto a tubular forming die, inserting the sleeve while in a hydrated state into a sheet metal supporting tube of complemental shape and size such that adjacent surfaces of the tube and sleeve will be in contacting engagement and then drying the assembly to remove the water resulting in forming of a hard, solid structure refractory liner that is fixed in the tube solely through frictional forces and adhesive bonding by the binder materials. A modified duct formed by the same methods includes a composite refractory liner formed from a plurality of tubular liners that each have their own respective structural, physical and thermal characteristics.
