Abstract

제강더스트를 첨가하여 소결광 제조시 발생하는 NOx의양을 억제하는 방법으로 특히 제강더스트와 연료를 제외한 모든 소결원료를 혼합 및 조립하고, 이 조립원료에 제강 더스트와 연료의 혼합물을 첨가하여 조립함으로써 효율적으로 NOx발생을 억제할 수 있어 별도의 NOx제거 플랜트 설비 또는 고염기도 조업등 종래의 방법과는 달리 소결광 제조원가 절감 및 환경 오염방지에 기열할 수 있다.By adding steelmaking dust to suppress the amount of NOx generated in the production of sintered ore, all sintered raw materials except steelmaking dust and fuel are mixed and granulated, and the mixture of steelmaking dust and fuel is added and assembled efficiently. Since it can suppress the generation of NOx, unlike conventional methods such as separate NOx removal plant facility or high base operation, it can contribute to reducing the cost of sintered ore manufacturing and preventing environmental pollution.
