Lime/limestone addition is frequently based on a pH monitoring procedure. However, the method has been proven to be very unreliable. When the pH system does not follow boiler load fluctuations, pH instability occurs, possibly causing serious scaling problems. Shutdown of the FGD system can result. Two common reasons for failure of pH measuring
An SO 2 scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coalfired power plants. A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas. There are some ...
