Atomizing technologies and air pollution control solutions

Custom-Designed Technologies for the Metals & Mining Industry

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.
