CFD Modeling of Multiphase Flow in an SKS Furnace with New Tuyere Arrangements

Abstract There has been a great deal of focus on the optimization tuyere arrangements in SKS bottom blown copper smelting furnaces since last decade, as improved furnace operation efficiency technology potential that cannot be ignored. New – x + 0 deg with 14 tuyeres are proposed this research paper. Using previously verified numerical model, CFD tests velocity distribution and wall shear stress for scaled-down models were conducted, constant total volumetric gas flow rate, different operating parameters cross-section geometries. The results indicate that, at relatively low injection speed compared optimized arrangement, although +0 unable to supply enhanced agitation typical round furnaces, they achieve better performance elliptical furnaces. At comparatively higher speed, can improve while maintaining an acceptable side wall. enhancement − essentially attributed stronger interactions between bubble plumes walls. To further exploit advantages new arrangements, angle was confirmed by full-scale model simulation.
