An Eulerian-Eulerian computational fluid dynamics (CFD) model of the gasification processes in a coal bubbling fluidized bed (BFB) is presented based on the experimental setup taken from the literature. The base model is modified to account for different parameter changes in the model setup. The exiting gas compositions for the base model have been averaged over time and validated with experimental data and compared to the exiting results for the different parameter models. An extensive study is also carried out which considers the variation of different parameters such as bed temperatures, bed height, bed material, heat transfer coefficients, and devolatilization models influenced the gasification processes in different ways. Such an extensive parametric study has yet to be carried out for an Eulerian-Eulerian coal gasification model.
