Development of methods for assessing the safety of dust removal facilities in environments with a danger of explosive atmosphere

Due to the tightening of air pollution laws and employee safety regulations, manufacturers are being forced pay more attention removing dust particles from released by their installations. This requires them install large complex collection systems in all facilities. Dust include points where entrained drawn into a system pipes that carry air, fans feed movement collectors separate air. mostly dry type. Dry-type divided cyclones bag-type collectors. As can create an explosive atmosphere, it is necessary assess risk explosions establish appropriate measures prevent explosion or, as case may be, limit effects explosions. The paper presents aspects related evaluation at removal installations with emphasis on initiating / atmosphere through electrostatic discharges.
