PROCESS AND INSTALLATION FOR CALCINATION OF PULVERULENT AND GRANULAR MATERIALS

机译:粉状和颗粒状材料的计算过程和安装

摘要

A method of burning pulverous or granular material in a plant including a suspension preheater and a rotary kiln having an integrally mounted planetary cooler for cooling the burnt material exiting from the kiln by means of air subsequently used for combustion and preheating in the plant. The method comprises directing the heated cooling air from the planetary cooler into the rotary kiln, dividing the heated cooling air into two streams, directing the divided cooling air out of both ends of the kiln in its divided streams, directing at least one of the streams of the heated cooling air into the rotary kiln and utilizing the stream as combustion air in the rotary kiln, thereafter directing the stream as part of a waste gas out of one end of the kiln to the preheater for use in preheating the raw material fed into said preheater, drawing the other stream of heated cooling air out of the other end of the kiln and directing said other stream of cooling air to the suspension preheater for use in preheating raw material fed into said preheater. An apparatus for practicing the method of the invention is also disclosed.
