Experience in Saving Energy and Reducing Harmful Emissions from the Agglomerationof Ferrous Materials

Abstract

We examine the results of the industrial implementation and operational experience of small ignition furnaces in sinter machines of various domestic and foreign enterprises. The furnaces are equipped with automatic thermal management systems. We assess the use of hot air both as input into the burners, as well as blown into the cake layer beyond the furnace. It is shown that the sintering gas recirculation, recovered after the vacuum chamber, can significantly reduce emissions into the atmosphere, reduce the consumption of solid fuels and the mass fraction of minutiae in the final agglomerate. We study different variants of organizing the recycling of sintering gas.
