Biomass gasification as a means for avoiding fouling and corrosion during combustion

Gasification of biomass at 600-800 degrees C can produce an effluent gas fo r use in a combustor for power production after removal of the solid produc ts of gasification by hot gas cleanup (e.g., aspen wood). This will avoid t he fouling and/or corrosion often found in biomass combustion. Biomasses wh ich form liquids below 800 degrees C (e.g., wheat straw) require the use of additives which raise the lowest temperatures for the presence of inorgani c liquids to over 800 degrees C. This alternative path for avoiding the fou ling and corrosion found during combustion of many biomasses probably can b e applied to a broad range of analogous materials.
