Document Type and Number:
Japanese Patent JPH0510289
Kind Code:
B2
Abstract:
A method for the heat treatment of finely granular material, particularly for the production of cement, employs a multi-stage cyclone preheater, a rotary tubular kiln, a cooler, and a single kiln off-gas line which is formed between the rotary tubular kiln and the cyclone preheater and is flown through substantially in upward direction by the off-gasses of the rotary kiln and to which tertiary air is fed in two partial-streams for the combustion of additional fuel. The method employs steps of feeding fuel to a lower partial stream of tertiary air, directing material to be treated above a second partial stream of tertiary air, and applying precalcined material in countercurrent with the off-gas line below the tertiary air.
