Studies on the Heat Recovery from the Sinter Cooler, S.C. ArcelorMittal Galati

Abstract

Heat recovery to the sinter plant is a means of improving the efficiency of the sintering process. The hot agglomerate must be cooled down. The heat recovered from the sinter cooler is used to preheat the combustion air for burners in the ignition furnace. In addition to heat recovery, the system helps decreases and particulate emissions, and improves sinter productivity, yield and cold resistance. This makes a recirculated type system more efficient than a non-recirculated type.
