Regeneration of lime from sulfates for fluidized-bed combustion. [Patent application; US DOE]

Patent ·
OSTI ID:6330144
;
In a fluidized-bed combustor the evolving sulfur oxides are reacted with CaO to form calcium sulfate which is then decomposed in the presence of carbonaceous material, such as the fly ash recovered from the combustion, at temperatures of about 900/sup 0/ to 1000/sup 0/C, to regenerate lime. The regenerated lime is then recycled to the fluidized bed combustor to further react with the evolving sulfur oxides. The lime regenerated in this manner is quite effective in removing the sulfur oxides.
