摘要： Apparatus for the heat treatment of fine material comprises a multi-stage cyclone preheater, a rotary kiln and a calciner supplied with tertiary air from a cooler for precalcination of the preheated fine material. The tertiary air pipe is narrowed at the point where it joins into the calciner. In this way an intensification of the mixing together of material, fuel and gas is achieved as well as an improved combustion, particularly fuels which are slow to react.

摘要： Fine-grained material adapted to be fired in a furnace is discharged from a preheater into a gas conduit extending from the furnace to the preheater and through which a stream of hot gases pass. The conduit is shaped to deflect the gas stream and concentrate it along one side of the conduit in the area of introduction of the material to the conduit. Below the area of introduction of material to the conduit fuel burners provide a heating zone through which the material falls. The concentration of the gas stream along one side of the conduit assures entrainment of the material in the gas stream and passage of the material again through the heating zone. Above the area of introduction of material to the conduit the latter is shaped to deconcentrate the gas stream and permit some of the material entrained therein again to fall downwardly through the heating zone, following which such material is reentrained in the gas stream.

摘要： 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.
