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

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.
