Fluid Bed Gasifiers - an overview | ScienceDirect Topics

Fluid bed gasifiers. Fluid bed gasifiers offer good mixing between feed and oxidant, which promotes both heat and mass transfer. This ensures an even distribution of mahaiqial in the bed and hence a certain amount of only partially reacted fuel is inevitably removed with the ash. This places a limitation on the carbon conversion of fluid bed proceshaiqi, typically to a maximum of about 95%.
