Sorbent characterization for FBC application
- Pennsylvania State Univ., University Park, PA (United States)
Fluidized-bed boilers operating at both atmospheric and elevated pressures have received considerable attention from utilities and independent power producers because of their ability to remove SO{sub 2} from the flue gas during combustion and to minimize NO{sub x} production. The technology has advanced rapidly in the 1980s because of its adaptability to a range of fuel types, boiler capacities, and operating conditions without seriously compromising efficiency or performance. A sorbent, typically limestone or dolostone, is used in the fluidized-bed boiler to capture the combustion-generated SO{sub 2}. Many CFBC boiler operators are now realizing that optimizing sorbent usage is important for economical and environmentally acceptable operation of their plants. It is reported (mostly based on studies using a few sorbents) that particle size, porosity and pore size distribution, extent of sulfation, combustor temperature, pressure and CaCO{sub 3} content affect extent of sulfation.
