Cyclone Boiler - an overview | ScienceDirect Topics

Coal-fired power plants may use SO 2 scrubbers to meet the requirements of Phase II of the Acid Rain SO 2 Re-duction Program. Additionally, the use of scrubbers can result in reduction of Hg and other emissions from com-bustion sources. This paper presents a comprehensive review of the state of the art in FGD technologies for coal-fired boilers.
