Spray Dryer Absorber Power Plants

Spray Dryer Absorbers SDA Babcock & Wilcox

SDA systems are designed for utility boilers typically burning low to medium sulfur coals, smaller utility applications and combined HCl and SO 2 control on waste-to-energy units. B&W’s typical SDA system installations meet or exceed air quality regulations and operate at 90 to 95 percent SO 2 removal efficiency, with some plants running as high as 98 percent.
