Abstract:The oxygen blast furnace (OBF) is a new ironmaking technology. The coke rate and carbon dioxide emission can be decreased greatly in the OBF process. In the OBF process, the room-temperature oxygen is blown and the preheated top gas of CO 2 stripped is recycled into the furnace. The recycled gas has various positive and negative effects on coal combustion. To further understand the effect of recycled gas on coal combustion and increase the coal burnout as much as possible, it is necessary to carry out some investigations. In the study, a three dimensional coal combustion model is developed to simulate the oxygen/coal lance-blowpipe-tuyere-raceway of a OBF. The effect of recycled gas temperature was investigated.

“…However, computational fluid dynamic (CFD) provides a new method for the investigation of PCI in BF. Many investigations on the coal combustion in blast furnace (BF) using CFD have demonstrated its reliability and superiority [6][7][8][9][10]. Therefore, in this study, the coal combustion in theBF is investigated using CFD.…”

Abstract:In this paper, a numerical model simulating the lance-blowpipe-tuyere-raceway of a blast furnace has been developed. The coal flow and combustion along the coal plume are studied. The effect of the lance tip area and position on coal combustion is investigated.. The simulation results indicate that the coal burnout is increased with increase of the lance tip distance from the raceway. The coal burnout is also increased with increase of the lance tip area, and the influence is very obvious.
