Entstaubung heißer Gase

Abstract

Dust extraction from hot gases. The introduction of new, energy‐saving, and low‐pollution technologies required development of highly efficient systems for purifying dustloaden hot gases at temperatures between 500 and 1000°C and pressures between 1 and 20 bar. The present state of dust removal is described for separators utilizing gravitational forces, electrical effects, filtration, and wet techniques, and typical applications of present‐day dust extraction from hot gases are presented. Possible developments with a view to extending the scope of dust extraction are indicated.
