Flue Gas Desulfurization System India, Flue Gas ...
Why FGD? Indian coal contains sulphur in the range of 0.2 per cent to 0.7 per cent by weight. With this sulphur content, it is estimated that domestic coal-based plants emit Sulphur Dioxide (SO2) in the range of 800-1,600 mg/Nm3. This is way above the

Flue-Gas Desulphurization - an overview ScienceDirect
K.J. Ladwig, G.M. Blythe, in Coal Combustion Products (CCP's), 2017 3.1 Introduction. Flue-gas desulfurization (FGD) systems have been used to limit the release of sulfur dioxide (SO 2) from coal-fired power plants since the late 1960s.The solids produced by FGD systems represent the second-largest coal combustion product (CCP) stream by volume, exceeded only by fly ash.

The Selection and Application of Anticorrosive Materials ...
1. Introduction. At present, with the national restrictions on mining and the reduction of high-quality limestone stock, many cement plants have to use low-grade limestone, with sulfur content ranging from 0.2% to 2.0%, resulting in excessive SO 2 emission concentration in the flue gas from the kiln tail, and some enterprises even reach a high emission concentration of about 3000 mg/Nm 3.
