Abstract


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. At high-grade burden and high parameters of the combined blast, dependence of coke consumption rate on PC amount is linear up to a high rate of PCI. At unfavorable burden and technological conditions dependence of the main furnace operating parameters on PC rate has extreme character. High efficiency of PC use can be achieved at the different conditions due to optimization of the technological regime.
