Environmental Equipment: Sulfur Dioxide Control

Since 1971, B&W's flue gas desulfurization (FGD) systems, or scrubbers, have operated efficiently, economically and reliably.

Our FGD technologies offer the highest SO₂ reduction levels in the industry.

We are a full-scope supplier. In addition to providing flue gas absorber modules, we can supply complete scrubbing systems, including reagent preparation, dewatering and recycling, and related system equipment.

Our FGD products include:

• Wet FGD systems: Spray tower scrubber design used for SO₂ control, with patented tray design for more uniform flue gas distribution and improved absorption. Reagents include limestone; also lime, magnesium-enhanced lime, sodium carbonate and ammonia.
• Dry FGD systems: A rotary atomizer delivers a slurry of an alkaline reagent into the hot flue gas to absorb the SO₂ - principal alternative to wet scrubbing for SO₂ control on utility boilers burning low sulfur coals; also popular for smaller utility and industrial applications and for combined HCl and SO₂ control on waste-to-energy units. Reagents include lime slurry and optional recycled flyash.
