A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.
Oct 04, 2009 Flue gas desulfurization (FGD) is a technology used to remove sulfur dioxide (SO 2) from the exhaust flue gases of fossil fuel power plants.Fossil fuel power plants burn coal or oil to produce steam for steam turbines, which in turn drive electricity generators.. Sulfur dioxide is one of the elements forming acid rain.
