Metals & Mining

Babcock & Wilcox provides custom-designed atomizing technologies and air pollution control solutions for the non-ferrous metallurgical industry, including aluminum, copper, nickel, zinc, and precious metals producers.

By lowering the temperature and conditioning the gas stream, the system protects downstream equipment from damage and improves the efficiency of downstream air pollution control equipment, such as baghouses and electrostatic precipitators.

• Horizontal and vertical coolers
• Waffle hoods
• Cu and Ni converter off-gas cooling
• Roaster off-gas cooling
• Aluminum anode bake furnace off-gas cooling

To reduce emissions from furnace and converter off-gases, we offer:
• SO2 control using the B&W spray dryer absorber 
Wet electrostatic precipitators for collecting fine particulate and sulfuric acid mists from SO2-rich gas streams

Water-tube Package & Industrial Boilers

Water-Tube Package Boiler
B&W is a leading supplier of water-tube package  and high-capacity industrial boilers for start-up and auxiliary power. Units are shop-assembled or modularized with bottom-supported designs for oil, natural gas and other gaseous and liquid fuels. Capacities up to 1,200,000 lb/h (544.2 T/h) are available, depending on type and design features.    

Spray Dryer Absorber (SDA)

SDA Spray Dryer Absorber
Our SDAs provide effective control of SOx and HCl by the injection of calcium, potassium or sodium-based slurries.

Babcock & Wilcox is the exclusive North American licensee of GEA Process Engineering for the GEA Niro SDA process.  Our proven SDA systems have been optimized to reduce long-term power and lime consumption, while plant owners benefit from lower operation and maintenance costs.

Wet Electrostatic Precipitators (WESP)

ESP for Metals and Mining
Our electrostatic precipitator technologies deliver maximum particulate removal efficiency with proven reliability and reduced operating and maintenance costs.

The wet ESP offers highly efficient control of submicron particulate, heavy metals, acid mists, and condensed metal fumes and organics.
