Flue Gas Desulphurization (FGD) When coal is burned, generally 90% or more of the sulfur present in it is emitted into the atmosphere as SO2. FGD reduces emission of SO2 up to 97 % Not installed in most power plants in India as it will increase generation cost. It is felt earlier not required for law sulphur Indian Coal. Height of Stack is specified for Control of SO2.

The regions as identified under level-II can be covered subsequently under the next phases seeing the performance of FGD system in Level-I. Presently no action is required for the plant located
The flue gas desulfurization (FGD) plant removes sulfur dioxides (SO 2) from flue gas produced by boilers, furnaces, and other sources. Mitsubishi Power effectively contributes to the prevention of air pollution through its wet limestone-gypsum FGD process and seawater FGD process, and both processes can treat a large range of SO 2 concentrations for greater plant reliability and economics.
The studies related to removal of SO2 started in 1860s when experiments were performed on absorption of SO2 in Water. First FGD project on a Utility was put into operation at Battersea Station, London Power Company in 1931. In 1935, FGD was installed at Swanssea Power Station using Lime slurry injection. In 1938, the third FGD system was ...

FLUE GAS DESULFURIZATION (FGD) FOREWORD. When coal is oxidized (burned) as fuel, the elemental sulfur it contains is converted to SO 2. Some of this SO 2 is converted to SO 3 when oxygen leftover from the combustion process causes further oxidization in the boiler. A system equipped with a selective catalytic reducer (SCR) to reduce NO

Jun 17, 2017 The tariff implication of FGD, considering an operational life of 15 years, auxiliary power consumption of 1.5 per cent and plant load factor of 62 per cent, is likely to be around Re 0.32 per kWh. However, it is being argued that the cost implications could be higher, considering the loss on account of the shutdown and raw material costs.
