Fugitive and non-fugitive dust generation and control in conveying of powders: reality, technology and human attitude

Abstract

Dust is often perceived differently by individuals from diverse backgrounds and types of industry where “dust” is generated. This usually leads to ramifications related to technological, economical and societal issues. Dust is always generated whenever a granular material is conveyed, no matter how it is moved. In the conveying of bulk solids the prevention of generated dust, fugitive or non fugitive, is almost an impossible task while its control is always feasible. The control of dust generation starts with the recognition that its generation is a problem that has to be dealt with in voluntary or non-voluntarily fashion. The extent to which plant personnel can achieve the desired dust control depends on many parameters such as the nature of powder handled, the overall process, the plant environments, dust control technology, economic reality, heath safety issues, and most importantly the human attitude. The presentation in this chapter is intended to dwell on the above topics.
