Abstract
A rotary kiln having a row of planetary cooler tubes disposed around its outer periphery and carried by individual metal mountings on the kiln casing, adjacent mountings abutting against each other in their areas bordering on the kiln casing and being spaced apart in their areas remote from the kiln casing, for minimizing changing temperature induced stresses imparted therefrom to the kiln casing during operation.
Claims6
A rotary kiln comprising a casing having an annular peripheral wall, a row of substantially parallel circumferentially spaced cooler tubes disposed around the periphery of said casing, and a plurality of individual heat conductive mounting plate means for said tubes, separately secured to said casing wall, the radially inner region of each individual mounting plate means near the casing being in side edge abutment with the corresponding inner region of each adjacent mounting plate means circumferentially of said casing and outer regions of adjacent mounting plate means located radially outward of said inner regions being spaced from one another in non-heat conducting relation circumferentially of said casing, the abutting radially inner regions of said plurality of said mounting plate means forming a substantially continuous annular link extending peripherally around said casing, and said tubes being disposed radially outwardly of said link.
