Sulphur dioxide (SO2) is mostly emitted from coal-fueled power plants, from waste incineration, from sulphuric acid manufacturing, from clay brick plants and from treating nonferrous metals. The emission of SO2 needs to be abated. Both wet scrubbing (absorption) and dry or semi-dry (reaction) systems are used. In the dry process, both bubbling and circulating …
These temperatures are lower than the flue gas temperature at the air heater outlet, which gives a recoverable difference in flue gas enthalpy. It can be used to re-heat the flue gas upstream of the stack or (if the flue gas from FGD is discharged into the cooling tower or wet stack) to heat any medium, to increase the efficiency of the unit.
For FGD scrubber sludge to be a useable construction material, the sludge must first be dewatered and then stabilized or fixated. Fixated FGD scrubber material is generated, dewatered, and stabilized at coal-burning power plants that require scrubbing of flue gas to reduce sulfur dioxide emissions.
