Abstract:
A two dimensional numerical model developed for the gasification zone of a fixed bed downdraft biomass gasifier. The model is based on the conservation equations of mass, energy and momentum written for the solid and fluid phases coupled with the chemical kinetics. The obtained numerical results are compared with existing experimental and numerical data and a reasonable agreement is observed. The temperature profile, gaseous concentrations distribution and velocities fields are investigated for the two-dimensional domain. The results show that the bed temperature and the reactivity of the char are the main variables influencing the conversion of char to syngas in the fixed bed gasifier.
