The modeling research of the ash-agglomerated fluidized bed gasifier
灰熔聚流化床气化炉的CFD模拟研究

In this paper, through the CFD modeling of the ash-agglomerated fluidized bed gasifier, the gas molar concentration distributions in the bed with the influences of the oxygen flow rate from the central nozzle, the steam flow rate from the distributor and the pressure of the bed are studied. The effects of the different operation conditions on the different reactions are deeply explored and then the law about how the operation conditions work on the gas concentrations in the gasifler can be explained.
