rates of 30 90%. For many coalfired plants, the best option presently for consistent, high mercury removal efficiencies (> 90%) is sorbent injection followed by a fabric filter. In the future, standards will likely be enacted for stationary sources limiting particulate matter of micron diameter and less.
StandAlone Fabric Filters • Coalfired utility power plants • Solid fuel industrial boilers (stokers) ... a fabric filter may be coupled with sorbent injection systems for collection of both gaseous and solid ... the fabric filter is deposited over the entire surface of the filter bags. Flue gas flowing through the sorbentcoated filter ...
Dust from the ESP and Bag Filter is transferred to the dumper. In F Furnace cast house dust is controlled by dust extraction system, same dust collection mechanism follow as in stock house. In coal injection plant, the coal fine laden gas pressure in the bag filter should be optimum so that the bag filter vent gate does not open.
