This paper presents the results of recent tests of a new type of sorbent useful for emissions control. The sorbent, referred to as thermally active marble (TAM), comprises a class of naturally-occurring metamorphic calcium carbonates. TAMs break down upon heating in combustors more evenly and with higher reactivity than limestone, resulting in better calcium utilization rates. Use of TAMS may also reduce NOx and CO emissions, excess air consumption and unburned carbon, and also improve combustion efficiency. In a full-scale (90 MW) demonstration comparing TAM to limestone, the Ca/S improved from 2.6 to 1.5 or better. Unburned carbon in fly ash decreased significantly and NOx levels were also reduced.
