Caldyn - Model ABR - Desulphurisation System without Residual Water - Brochure

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 before the inlet to the scrubber by water injected with two-phase nozzles CSL. In the scrubber the pollutants are removed by atomization of lime and in a second stage by atomization of fresh water, thus achieving the requested clean gas concentrations.
