Electrostatic precipitator (ESP) is a kind of dust collector which uses static electricity to separate particles from airflow. ESP is suitable for small particle capture. Its dust removal efficiency is above 99% in industrial applications. It has a large flue gas treatment capacity, high automation degree, and low resistance.

Dust explosions are very similar to gas explosions. Depending on the containment configuration, if any, a pressure rise can take place. An ignition source (BS EN 1127) typically causes a primary explosion, which provides the energy and promotes airborne dusts, resulting in a secondary explosion, which is generally much more serious than the primary.
