灰熔聚流化床气化炉的CFD模拟研究
-
摘要: 通过CFD模拟了灰熔聚流化床气化炉,考察了操作条件包括中心管氧气量、分布板水蒸气量以及操作压力对流化床气化炉的气相浓度分布的影响。剖析了不同操作条件对化学反应的影响,解释了其对气化炉产气组成的作用原理。Abstract: In this paper, through the CFD modeling of the ashagglomerated 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 gasifier can be explained.
