Abstract

Abstract

Based on the mathematical model of pulverized coal combustion in raceway under oxygen-rich high PCI rate at Pangang 4^#BF, when coke rate and blast temperature are 580kg/tFe and 1050℃ respectively. if injected coal rate exceeds 155kg/tFe, blast oxygen-rich rate should be over 2%, blast furnace operate smoothly. When injected coal rate exceeds 210kg/tFe, even if blast oxygen-rich rate reaches 10%, because a large amount of pulverized coal is not combusted, blast furnace can’t operate smoothly.
