Process for improving the oxidation in the lime scrubbing process to bind acid constituents such as SO2, HCl etc.

摘要

In order to avoid an impairment of the thermal efficiency with too high an air excess in the combustion chamber system, according to the invention it is proposed that air and/or oxygen or air and/or additional oxygen-donating chemicals are fed during the scrubbing process, preferably upstream of and/or within the scrubbing water feed. The power station boiler for utilising fossil fuels is operated so that the oxygen content in the flue gas is greater than 5.5 %.
