dry fgd system
The dry FGD, or dry flue gas desulfurization system, is a new drive against air pollution. SO 2 To scrub sulfur dioxide, a substantial polluter, from flue gases produced by burning fossil fuels in power stations. The system's technological features include a spray dryer absorber, which combines flue gas with a lime or limestone slurry. The mixture responds to become solid calcium sulfite and sulfuric acid, which are then arrested in a cloth filter. The dry FGD system has a wide range of uses, from coal-fired power stations to industrial boilers. It's efficiency in pulling the SO 2 out of flue gases can greatly reduce the environmental impact of these installations. So the industry is finally paying for this benefit.
