REDUCTION OF DUST AND GAS EMISSIONS IN IRON ORE SINTERING PLANTS BY RECIRCULATION OF WASTE GASES

摘要

Laboratory experiments and trials in Huta T. Sendzimira resulted in development and implementation of industrial technology and equipment making it possible to recirculate a proportion of waste gases (some 20-22 percent or 60000-70000 std cu m/h) back to the sintering belt. Over a period of more than 6 months it was confirmed that such recirculation of waste gases resulted in significant reduction in emission of harmful gases (especially CO and SO_2) and dust without adverse effects on sintering plant operation and quality of sinter.
