Prediction of Producer Gas Composition for Small Commercial Downdraft Gasifier

H. Roesch, J. Dascomb, B. Greska & A. Krothapalli
The goal of this study was to produce a model predicting the composition and heating value of producer gas made from a small scale (20­250 kWth), down­draft gasifier. Due the non­ideal conditions in this type of gasifier, classical thermodynamic equilibrium models are inaccurate. A more reliable prediction model for gas produced in a system of this size and type is needed. Eight biomass feedstocks were gasified and analyzed for this study. The pelletized feedstocks chosen...
