摘要: Abstract Flue gas desulfurization (FGD) in a CFB at moderate temperatures with the T–T sorbent, hydrated calcium-based sorbent was numerically simulated using Eulerian approach two drag models for heterogeneous gas–solid flow, one is an EMMS-based theoretical model (QL-EMMS), other experimental (O-S). The QL-EMMS analyzed terms of cluster parameters, reduction and modeling by comparing data results O-S model. Results heterogeneity index show that more accurate than models, but there are still some differences from due to inaccurate description solid volume fractions clusters. factors influencing temperature were then investigated based on Predictions efficiency reaction rate indicate higher homogeneous distributions lead efficiencies. time also has important effect desulfurization.
