As a new treatment of sulfur retention in circulating fluidized bed, the intraparticle diffusion of the gaseous reactant is examined based on percolation on a Voronoi tessellation of polyhedra representing the porous structure of calcined limestone added to the bottom of a circulating fluidized bed combustor. Model predictions on the effects of various operating conditions on sulfur retention efficiency are found to agree well with experimental data.
