Status of Flue Gas Desulphurisation (FGD) systems

2015-3-15  1. Introduction. The term Flue Gas Desulphurisation (FGD) system has traditionally referred to wet scrubbers that remove SO 2 emissions from large electric utility boilers. The FGD systems emerged in the industrial field of the coal-fired power plants and on some industrial processes in the early 1970s in United States (US) and Japan, and expanded rapidly in the 1980s in Europe.
