Thông tin mô tả:
A reactor design combining impinging streams and a circulating fluidized bed reactor (IS-CFB) was developed to improve the gas–solid mixing in fluidized beds. The Eulerian two-fluid model and a sulfation model for a CaO/fly ash sorbent were used for numerical simulations of a pilot-scale IS-CFB reactor, and the simulation results indicate that the introduction of impinging streams to a CFB reactor significantly improves the desulfurization efficiency from 89.5% to 95.1%, due to the more homogeneous radial particle volume fraction distributions and the much larger effective SO2 capture zone.
