The dry FGD process has the following advantages when compared to wet limestone FGD technology: 1. The absorber vessel can be constructed of unlined carbon steel, as opposed to lined carbon steel or solid alloy construction for wet FGD. Typically, for units less than 300 MW, the capital cost is lower than for wet FGD. Typically, for units larger than 300 MW, multiple module requirements causes ...
GIW® Minerals FGD Flue Gas Desulfurization Pump KSB offers a complete range of heavy-duty GIW® Minerals slurry pumps for FGD system scrubbers. Rugged GIW® Minerals slurry pumps provide high sustainable hydraulic efficiency, and long wear life at the lowest total cost of ownership.
During the first years of the 1980s, the absorber sump of an FGD plant was generally equipped with a sparger grid to inject the oxidation air into the process. The little outlets of the pipes were easily plugged by the solids and led to significant investment, repair and maintenance costs.
Ducon Flue Gas Desulfurization systems can also recover up to 90% of oxidized mercury in the flue gas. Depending upon the reagent utilized, Ducon can select a packed tower, a spray tower or a Ventri-Rod Absorber (VRA™) (a proprietary Environeering unit) for the wet FGD application.
A typical lime/limestone Flue Gas Desulfurization (FGD) system consists of three major sub-systems: The reagent (lime or limestone slurry) preparation; The scrubber/SO2 absorber and mist eliminator, and slurry/solid waste disposal systems.
