Abstract

Fluidized bed combustion of a vacuum residue of Arabian Light was investigated using some kind of fluidizing materials composed by dolomite and Fe2O3. The highest combustion efficiency and desulfurization activity were obtained when the neutralized pricipitate of Yanahara mine derinage was used as the source of Fe2O3. It is produced when iron are stone is mined at Yanahara. It is mainly composed of iron sulfate and very cheap ion source. Fe208 from the neutralized precipitate of Yanahara mine derainage was loaded on the dolomite (YA-Dolomite).<BR>As a result CaO utilization attained 47%, NOx concentration was reduced to about 120 ppm by the addition of 1, 050 ppm of NH3. It seems that the desirable property of YA-Dolomite depends on its porous surface. YA-Dolomite could be used effectively at 5% excess air because of its high activity.
