Characterization of high-turbulence zone in slowly moving bed slagging coal gasifier by a 3D mathematical model

Under the operating condition (gasifying agent inlet velocity is 100 m/s, and the original and burnout sizes of coal particles are 15 and 4.35 m), an arch shape of high-turbulence zone is predicted as shown in (a), and the profile of high-turbulence zone on the symmetry plane is also shown in (b).48
