Fgd Flue Gas Velocities In Chimney

flue gas desulfurization ekato,ekato is world market leader for agitators in flue gas desulfurization, having sold more than 12,000 agitators in over 1,500 fgd-plants worldwide. since 1979, when the fgd market rose in europe and the usa due to more stringent emission limits, ekato equips coal fired power plants with agitators specifically designed for the extreme demands on.bw learning center articles babcock wilcox,gas velocity between the plates is also an important factor in the collection process since lower velocities permit more time for the charged particles to move to the ces and reduce the likelihood of migrating back into the gas stream (re-entrainment). a series of ce and de sections is generally necessary to achieve overall particulate collection requirements..
