Within a fluidized bed boiler, coal is burned at 850°C, while limestone is added in the boiler to trap (sorb) the acidic SO2 gas before its atmospheric emission. This process has been developped to minimize emissions of pollutants such as SO2 and NOx. Two kinds of residues are produced : bed ash extracted from the bottom of the boiler, and fly ash resulting from dust filtration of the flue gas. Depending on coal sulfur content, ashes may have high sulfate content. In this case, ashes cannot be… CONTINUE READING
