For thermal power plant, the FGD full form has many practical advantages so that it is worth taking and implementing. First and foremost, FGD systems dramatically reduce air pollution They cut way back (or "slash") on the amount of sulfur dioxide that is released into Earth's atmosphere.lt would be because of this reduction that we breathe cleaner air without having so many sore throats, not as much acid rain, and fewer lung diseases. This reduction directly translates into larger life expectancy, healthier air for all to enjoy pollution problems also decline in step. Second, by installing FGD technology, thermal power plants can escape costly penalties incurred for breaking environmental rules. Third, the gypsum so produced is a valuable biproduct capable of offsetting some of the operating costs Also, modern FGD systems are energy-efficient designs that contribute to reducing overall plant efficiency. Finally, investment in FGD technology demonstrates a company's commitment to environmental stewardship and corporate responsibility.
