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 Desulphurization. FGD material is the product of an FGD process that typically uses a high-calcium sorbent, such as lime or limestone. From: Clean Electricity Through Advanced Coal Technologies, 2012 Related terms:
Flue Gas Desulphurisation. Flue Gas Desulphurization (FGD) technology for gaseous pollution control. Air pollution in thermal or any process plants occur when chemical fumes, particulate matter, product, or any odours are released into the atmosphere. These emissions can contain harmful oxides of Carbon, Nitrogen and Sulphur which adversely ...
Before the flue gas reaches the absorber tower, it passes through a heat exchanger. The purpose of the heat exchanger is to cool the flue gas into the FGD to 90 degrees C. This heat is then used to reheat the cooled, treated flue gas as it passes back through the heat exchanger where it is reheated to above 80 degrees C to give it the buoyancy

NaHCO 3 + HF → NaF + H 2 O + CO 2. Generally, the flue gas temperature is between 140 and 250 °C. Due to the high activity of sodium bicarbonate adsorbents, a slight excess of sodium bicarbonate (stoichiometric factor between 1.1 and 1.3) is usually sufficient. Due to transportation and storage, sodium bicarbonate raw materials are usually ...
Flue Gas Desulphurization (FGD) The combustion of coal and oil supply a significant part of the world's present energy demand. Sulphur dioxide (SO2) is released during the combustion of these fuels.
