Quasi-dry flue gas cleaning (spray absorption)

For the quasi-dry flue gas cleaning, suspensions or solutions are distributed in the flue gas flow by means of a spray absorber with rotary distributor or two-component nozzles.

The acid flue gas components are absorbed in alkaline droplets with simultaneous water vaporization.

For the separation of organic pollutants and heavy metals, an adsorbent (e.g. coke dust) can be added upstream, in or downstream of the spray absorber.

The reaction products are separated in a downstream dust filter (fabric or electric filter).
