32.流動層石炭ガス化炉グリッドゾーンにおける反応の解析

抄録

The local compositions of gases of a jetting fluidized bed coal gasifier were experimentally measured. A numerical model for considering local behavior of gases and solids was developed to apply to prediction of the local gas compositions. The numerical results were compared with the experimental ones. The effects of static bed height on local progress of reactions were discussed. It was confirmed that combustion mainly occurred in the grid zone while steam and CO_2 gasifications mainly occurred in the bubbling zone.
