The fluidized bed steam-oxygen-char gasifier is modelled by treating the bed as one in which the solids are well mixed and the gases are in plug flow. This model permits a detailed analysis of the combustion zone. The entire reactor is assumed to be at a uniform temperature. From the results of the model calculations, it was concluded that the assumption of negligible combustion zone thickness made in the earlier two papers is acceptable This model predicts higher total carbon conversion and methane mole fraction in the product gas than the lumped model analysed in an earlier paper.
