This paper describes a unique multi-stage wet scrubber installed on a 420,000 lb/hr (MCR) coal/oil swing boiler burning high sulfur coal (as well as collected Non-Condensable Gases from the Pulp Mill). This system accomplishes the goals of very high removal efficiencies (equaling that of a traditional Wet ESP) for both PM and SAM plus SO2/HCl removal - all in one wet scrubber. This …Get Price
FGD scrubbers are the most commonly used scrubbers on coal-fired utility boilers. These FGD units generally capture more than 90% of the Hg(II) in the flue gas entering the scrubber. Consequently, existing wet FGD scrubbers may lower mercury emissions by about 20% to more than 80%, depending on the speciation of mercury in the inlet flue gas.Get Price
