Wet flue gas desulfurization or scrubber systems are very effective in reducing sulfur dioxide (SO2) emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber where a mixture of water and pulverized limestone is sprayed on the flue gas. The limestone slurry reduces sulfur emissions by absorbing the SO2 contained in the flue gas. The limestone reacts
Wet flue gas desulfurization or scrubber systems are an excellent way of reducing the sulfur dioxide emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber. In the absorber a mixture of water and pulverized limestone is sprayed on the flue gas. The limestone slurry absorbs the sulfur dioxide (SO 2) contained in the flue gas reducing the emission of

[None of desulfurization processes (wet or dry) is really satisfactory; Reinluft process appears to be most satisfactory] (in German) Journal Article Johswich F - Brennst.-Waerme-Kraft Study on desulfurization of flue gases by the active carbon process using steam desorption (Part 4) - variation of properties of active carbon used on a test plant.
Additionally the use of scrubbers can result in reduction of Hg and other emissions from combustion sources. It is timely therefore to examine the current status of SO2 scrubbing technologies. This paper presents a comprehensive review of the state of the art in flue gas desulfurization (FGD) technologies for coal-fired boilers.
Flue gas desulfurization (FGD) is the current state-of-the art technology used for removing sulfur dioxide (SO 2) from the exhaust flue gases in power plants that burn coal or oil to produce steam for the steam turbines that drive their electricity generators. Sulfur dioxide is responsible for acid rain formation.

Are flue gas desulfurization (FGD) systems reliable and operable for scrubbing stack gas effluents from the combustion of high sulfur coal of the eastern United States? It is important to consider this question both in light of the recent large increase in

Important classifications of flue gas desulfurization (FGD) processes that have been tested on coal-fired boilers are shown in Figure 2-1. A major distinction is generally made between recovery processes which recover S02 in useful forms such as sulfuric acid or elemental sulfur and throwaway processes which produce a solid or liquid waste.
