2062818 9117384 PCTABS00008 An insulation assembly (10) for a helical recycle conduit (12) of a rotary reactor (14) having a rotating, horizontally-oriented, cylindrical chamber for burning materials therein and a quantity of particulate, inorganic material within the chamber for conveying heat energy to material to be burned. The insulation assembly includes a plurality of cylindrical shell elements (28), each enclosing a portion of the conduit and arranged in overlapping relation, a plurality of mounting rings (30), each attached to and extending radially from the conduit for supporting the shell elements at ends thereof, and a pumpable refractory mixture (58) substantially filling an insulation space between the shell elements and conduit. Preferably, only one end of each element is attached to a mounting ring, unattached ends overlapping the next adjacent shell element to form a continuous covering which contacts or expands longitudinally in response to thermal expansion and contraction of the enclosed associated conduit. The mounting rings are segmented and include slots (50) which permit expansion and contraction from the underlying conduit without destruction of the mounting ring.
