Model equations for slab type pellet consisting of spherical grains are solved numerically. It is shown that some of the generalised equations reported in the literature for slab type pellets with slab type grains and spherical pellets with spherical and slab type grains are equally applicable to a slab type pellet with spherical grains. A sensitivity analysis of the model to various parametric changes has been made and compared with experimental data on zinc sulphide oxidation to indicate the significance of the various assumptions. It is also shown that the model can be extended to solid‐consuming reactions as well. Experimental results on gasification of carbon with carbon dioxide reported in the literature were verified satisfactorily with the present model equations.
