DEF

A clean coal technology that uses pulverized coal mixed with limestone [and in which] limestone ... absorbs sulfur from the gases resulting from the combustion of the coal.

CONT

Atmospheric fluidized bed combustion (AFBC) is a process that reduces sulfur emissions from coal-fired electric-generating plants. The residue from this process is a mixture of alkaline oxides, calcium sulfate, and coal ash constituent. ... The best and safest use of AFBC residue in agriculture was as a substitute for agricultural lime.

OBS

The process reduces approximately 90 percent of sulfur dioxide emissions and causes a moderate reduction of nitrogen oxide emissions.

OBS

The fluidized-bed design for PFBCs is basically the same as that for AFBCs, the essential difference being that the former operates at higher gas pressures than the latter.
