When fuel switching or coal cleaning is not an option, flue gas desulfurization (FGD) is selected to control sulfur dioxide emissions from coal-fired power plants (except for fluidized-bed combustion systems, which is discussed later in this chapter). FGD has been in commercial practice since the early 1970s. It has become the most widely used technique to control sulfur …
