Chimneys for Operation without Flue Gas Reheating after FGD

Sep 12, 2016· Apart from redefined emission limit values for flue gas contents, a significant change (in the case of discharge by chimney) is the dropping of a minimum flue gas temperature of 72° C at the chimney outlet. For plant design, this means that reheating of the flue gases after wet flue gas desulfurization is no longer necessary.

FLUE GAS DESULFURIZATION - emerson

What is Flue Gas Desulfurization (FGD)? FGD is a set of technologies used to remove Sulfur Dioxide (SO2) from exhaust flue gases in coal, oil-fired, and waste- to-energy power stations. SO2 is a pollutant/irritant in air and a major contributor in the creation of acid rain. SO2 emissions are subject to strict environmental protection regulations.

Flue gas pretreatment is needed, which generally consists of two sections: one dedicated to NO 2 and SO 2 removal, and one dedicated to flue gas water saturation and cooling to 30–40°C. In addition, the implementation of a wet electrostatic precipitator can significantly reduce SO 3 aerosols, fine water droplets, and small particles.
