Depending on the dust concentration of the flue gas a cyclone is installed for pre-dedusting (optional). Lime slurry from the bottom of the scrubber is atomized into the spray absorber by nozzles. The lime reacts with the acid flue gas pollutants SO2, HF and HCl. For the removal of the dust and the dry reaction products a deduster MULTIWIR is used. After dedusting, the flue gas is saturated ...

Nitrogen oxides that cause pollution of the environment are converted to nitrogen and water by adding a reducing agent (urea solution or ammonia). With the SCR process the reducing agent is injected at comparatively low temperatures and the nitrogen oxides are reduced to molecular nitrogen using a catalyst. With the SNCR process the reducing agent is injected directly into the hot flue gas at ...
