56.流動層石炭ガス化炉内での石炭の凝集特性と反応特性

抄録

Agglomeration and reaction characteristics of various coal chars were investigated in a jetting fluidized bed coal gasifier. The level of carbon conversion was increased with decreasing carbon content, as properly expected. The effect of carbon content was observed especially in the grid zone; reactions of CO production and steam gasification proceeded for coals with lower carbon content. Agglomeration occurred below the softening temperature of coal ash.
