Abstract:
Gas dynamics and gas distribution in shaft furnace play crucial role in improvement of furnace productivity, product quality and reduction in natural gas rate. Optimum design parameters of gas distribution devises were investigated by means of mathematical modelling, pilot plant and industrial installation studies. New heat transfer co-current schematics of gas and material movement with self-reforming of natural gas in metallization zone, was invented, patented and tested at pilot plant. New Shaft furnace design and improvements where proposed and new gas distribution devises were implemented, providing savings in fuel rate, increase in productivity and improvements in quality of DRI.
