A Flue Gas Desulphurisation (FGD) system is majorly available in three variants – Wet Flue Gas Desulphurisation (WFGD), Spray Dryer Absorber (SDA) and Dry Sorbent Injection (DSI), each with distinctive capabilities for emission control. The systems use alkali reagent for Sulphur Dioxide (SO2) removal. In addition to SO2 removal, these systems also treat HCl, HF, SO3 and fly ash. The system is equipped with proven technology with the largest number of installations worldwide. Our system can achieve SO2, HCl and HF reduction with more than 97% capture efficiency.

Product Features
  • Wet FGD system is equipped with ALRD® Technology for achieving higher SO2 removal efficiency with lesser power consumption
  • SDA uses specially designed atomisers to form fine droplets of reagents for a better reaction
  • Two loop control concept in semi-dry system ensures efficient operation and better control
