Comprehensive calculation model for biomass gasification in updraft fixed bed gasifier

H. H. дoδpoxoTOB proposed an empirical model for coal gasification which improves the limitations of other theoretical models in engineering applications. With this method, a comprehensive calculation model for biomass gasification in updraft fixed bed gasifier was proposed based on the measured data of biomass pellets gasification in 3M13 gasifier. In this model, the yields of pyrolysis water, CO₂ and tar in carbonization stage of the original model was modified. In addition, equivalence ratio (ER) is introduced to amend the random eigenvalue n of C/N ratio in fixed-carbon gasification stage of the original model. The simulated results were compared with the actual experimental results and other scholars of the experimental data, which shows a largely satisfactory agreement and proves the effectiveness and reliability of this model.
