Blast furnace operation with pulverized coal injection at different technological conditions

摘要

Efficiency of pulverized coal injection(PCI)at two blast furnaces(BFs)in Spain and Ukraine which operate at different burden and blast conditions has been analyzed using Statistical methods, calculation of material and heat balances and a mathematical model. Effect of PCI on the parameters of blast furnace operation, pig iron quality and also on Interactions between process parameters has been studied.
