fgd system in thermal power plant
Consisting into any thermal power plant, the Flue Gas Desulfurization (FGD) system is mainly designed to reduce the emission of sulfur dioxide. Here's how it does that: The flue gas is scrubbed with lime slurry, and SO2 is removed before it goes out the chimney. The main functions of a FGD system are absorption of sulphur dioxide, conversion SO2 into gypsum, and adherence to relevant environmental laws. As far as the technology is concerned, FGD systems now feature advanced absorber technology, well-adjusted spray nozzles and efficient gypsum dewatering processes in order to realize these functions. With these features on board, more than 90% of SO2 can be taken out. This makes FGD a centerpiece for clean coal technology, as is it necessary to prevent air pollution from the burning of coal-based power plants worldwide.
