Title:
METHOD AND APPARATUS FOR REDUCING SULFUR RECIRCULATION AND/OR SO2 DISCHARGE IN PLANT FOR BAKING FINE PARTICLE
Document Type and Number:
Japanese Patent JPS58196837
Kind Code:
A
Abstract:
A method and apparatus for reducing the sulfur content and/or the SO2 emission in a system for calcining fine grained materials such as in the manufacture of cement utilizing a pre-calcining and a final calcining stage. The sulfur content of a process gas or of a material stream is determined and then is mixed with appropriate amounts of a dust or a raw meal in a reaction zone, the dust or raw meal containing sulfur bonding substances such as alkaline earth carbonates. The exhaust gas from which the sulfur compounds are removed by the sulfur bonding is separated from the sulfur containing solids and the exhaust gas and solids are removed from the calcining system.
