Feb 14, 2020 Kiln alignment, kiln loading, kiln crank, and diametrical clearance (creep) and other factors affect the ovality of the kiln: Tire ovality is determined by the design of the tire (thickness and width) at the pier. Shell ovality refers to tire ovality that transfers to the shell plate. Thus, shell ovality is never lower than tire ovality.

A rotary seal used to prevent the escape of contaminates from a rotating kiln incinerator. The rotating seal combines a rotating disc plate which is attached to the rotating kiln shell and four sets of non-rotating carbon seal bars housed in a primary and secondary housing and which rub on the sides of the disc. A seal air system is used to create a positive pressure in a chamber between the ...
