CFD MODELLING OF THE GASIFICATION OF COAL PARTICLES IN FLUIDISED BEDS

摘要

In this paper, two-fluid modelling is used to model a bubbling fluidised bed gasifier (BFBG) introducing two solid phases namely, sand and coal. The devolatilisation model and heterogeneous reactions are implemented and the gases produced are compared to experimental results, which shows a good agreement. The production of fuel gases is strongly influenced by the distribution of the solid phases, which requires accurate modelling of the multiphases involved.
