Abstract: A method and apparatus for the thermal decomposition of limestone or other mineral substance wherein the apparatus employed for carrying out the method combines a vertical shaft for the feed therethrough of the materials to be treated and a rotary hearth positioned therebeneath. The rotary hearth is contained within a substantially airtight enclosure and receives the downward flow of the materials from the central shaft and further processes the same to produce the desired resultant product.

Abstract: A method for sealing and cooling the component slot members between the stationary hearth and movable beam or beams in walking beam furnaces by injecting air into the slot in such a manner that the air jets create a stagnation plane within the slot to maintain an equilibrium with the furnace pressure while impinging on the beam members and simultaneously cooling it.
