Tim Hansen of Southern Research Institute describes the use of biomass at two spreader stoker boilers. With 15 percent biomass there was a net 10 percent CO2 reduction. SO2 and NOx were also reduced. In one unit when biomass was increased above 90 percent, condensable particulate emissions were reduced by more than 80 percent. There were also reductions in HCl, HF, and primary metals. |
