WebJul 1, 2024 · The desired increase on the pulverized coal injection is a complex and challenging task for the blast furnace technology. The reasons are mainly due to the gas flow control and unburned coal particles accumulation in the lower part of the furnace, which can generate unstable solid and liquids descending motions [8], [9], [10]. WebPulverized coal injection is a method for improving the performance of a blast furnace. Background Iron is a ... Blast furnaces keep on improving with adaptations arising from new technologies driven by rising global demand, yet the main chemical process remains the same. But process improvement cannot solve many of the problems associated with ...

WebJun 15, 2024 · Abstract. Recommendations are made for calculation of the total energy of the hearth-gas flux in pulverized-coal injection. That permits monitoring of the mean total energy and the energy at each tuyere in the blast furnace. On that basis, the penetration depth of the hearth-gas flux toward the center of the furnace may be regulated for each ... WebAug 12, 2010 · In the BFGCI process, granular coal (10%–30% through a 200-mesh screen) is injected into a blast furnace as a fuel supplement to decrease coke requirements, thus reducing costs.
