The aim of the present work is to predict the performance of the advanced biomass gasifier through computer simulation with computational fluid dynamics (CFD) software and to predict the flow field, velocity and temperatures at any spatial location. The computation is then extended to study the variation in gas composition and calorific value of the producer gas while increase the temperature. However validation of predicted results is essential to get confidence in the prediction procedure. Hence a quantitative comparison of the predicted results has been done with the experimental results taken from the Centre for Energy Technology, Osmania University, Hyderabad and was found to agree well with data available in CET.
