Abstrakt

The aim of this article is to develop a complete and detailed gasification model for a single solid fuel pellet. Three main objectives are achieved: a modified one-dimensional model using C++ code, a reliable results validation using experimental data from literature and an overview of the detailed onedimensional model results. This model is based upon the partial differential equations (PDEs) describing continuity, species transport, energy and pressure equations. All the equations are highly coupled and are solved using a central-differential scheme (CDS). A time-marching procedure is based on a fully implicit scheme. Both a grid independent validation and a validation against experimental data are given in the paper. The validation results show good agreement with the experimental data. The temperature profile, the definition of the end of each pyrolysis/gasification stages and the effects of sensible enthalpy are presented.
