Environmental Aspects Of Fluidized-bed Combustion

Reductions in S02 emissions from pressurized fluidized- bed combustion (PFBC) of 90 percent have been observed with a Ca/S ratio of less than 1, although the typical range is between 1 and 2. Future research in FBC S02 control will emphasize the confirmation of S02 control capability in large-scale units.
