Abstract

A plurality of cooling tubes are arranged in planetary fashion about the periphery of the kiln. An inlet for each cooling tube includes a transition member extending from one end of each tube, which transition member comprises the wall of an inclined frustum whose base lies on the end of the cooling tube in a plane perpendicular to the axis of the tube. An inlet tube has one end intersecting the wall of the kiln and its other end intersecting the wall of the transition member, two surface lines of the transition member being tangent to the inlet tube.
