Ore Sintering - an overview ScienceDirect Topics

2010-4-2  Of the eight CORINAIR (Core Inventory of Air Emissions (environment)) standard gaseous compounds, all except ammonia are known to be emitted by sinter plants. As described in Chapter 14 on iron ore sintering, sintering involves the combustion of fossil fuels like coal and coke breeze to generate the heat required for sintering reactions. Therefore, emissions from the sintering process arise primarily from the combustion reactions in the sintering bed on the traveling sinter
