Abstract
This paper reviews the development of technology in fine particle control. Electrostatic precipitators (ESPs), scrubbers, fabric filters, and novel devices were assessed to determine their efficiency. ESPs were found to be excellent in controlling fine particles: with an efficiency of 95%. Scrubbers were found to be less efficient than ESPs, primarily when the particle size decreased: efficiency became lower than 50% at 0.5 micrometers. Fabric filters proved to be a good method of collection, showing greater than 95% efficiency for particles between .3 and 4 micrometers. Fabric filters showed less ability, however, at handling high temperatures or corrosive gas streams. Nine novel devices were tested: most showed good control of smaller particles. One problem with the novel devices was their excessive use of energy. They would, however, be efficient particle collectors where waste heat is available in large amounts.
