KREBS Flue Gas Desulfurization Cyclones: High capacity Krebs gMAX® cyclones for reagent preparation and gypsum dewatering in FGD systems. Our Hydrocyclones and Technequip Knife Gate valves are used in Power Plants around the world.
FGD (Flue Gas Desulfurization) involves the treatment of flue gas from coal fired power plants. The main goal is to remove sulfur, particulates, and other chemicals such as mercury from the flue gas prior to environmental release. Governmental regulations by the EPA put limits on the amount of impurities which can be released into the air. The use of mixers to clean and scrub the flue gas is utilized to help power companies meet permitted limits on the release of controlled substances.
Pulsair Systems is a leading supplier of efficient mixing system for Flue Gas Desulfurization (FGD) for over 25 years. Our mixing process is more effective and energy efficient than mechanical top-entry agitators, side-entry agitators and other types of mixers that are expensive and require more maintenance and consume more energy.
FGD is Key to Coal-Fired Power Generation: Wet Flue Gas Desulfurization (FGD) is a process by which coal-fired power plants remove sulphur dioxide (SO2) before emitting their flue gas into the atmosphere. The water intensive scrubbing process requires a durable treatment technology as FGD blowdown wastewaters are highly contaminanted.
Coal combustion residuals (CCR) are generated during the power generation process and can include fly ash, bottom ash, boilerslag, and flue gas desulfurization (FGD) residuals. CCRs contain trace concentrations of heavy metals and therefore cannot be dumped or stored where rainwater can leach the metals. Liner systems can be used to contain the coal combustion by-products and protect them from leaching into the environment.
EVALED evaporators treat or minimize wastewater from the Power Generation Industry. Flue gas desulfurization effluents require different kinds of treatments depending on the type of fuel, water sources, and environmental regulations.
Flue Gas Desulfurization (FGD) involves the removal of sulfur dioxide and other acids from flue gases. Typical sources of acid gases include fossil fuel boilers, waste combustors, and other industrial applications such as refining and smelting. The Macrotek wet and dry FGD systems can achieve over 99% acid removal by using a variety of reagents, including caustic, sodium carbonate, lime and limestone, and waste alkaline solids or liquids.
