Babcock & Wilcox (B&W) dry flue gas desulfurization
(FGD) systems feature a combination of design components to provide a level of reliability and
sulfur dioxide (SO2) removal efficiencies that are among the highest in the industry.
B&W is the exclusive North American licensee of GEA Process Engineering A/S, Denmark, for the GEA Niro spray dryer absorber (SDA) process. The GEA Niro SDA is globally recognized by the power generation industry as the dry FGD technology of choice.
Features of the system include a unique flue gas dispersion system for optimal gas and reagent mixing, a low maintenance rotary atomizer with a slurry capacity that is among the highest in the industry, large SDA chambers, and a complete reagent recycle system. Benefits include high SO2 removal efficiency, integral mercury emissions reduction, low capital cost, high system availability, and low operation and maintenance costs.
