Verfahren zur Konditionierung von Rohgasen — Teil 1: Konditionierung durch elektrische Maßnahmen

The operating performance of plant for removal of particulates from gases can be positively influenced by crude gas conditioning and other additive measures. These processes involved introduction of additional material or additional energy into the plant. Set goals are the reduction of particle emissions, reduction of operating costs, adaptation to new boundary conditions, or the opening of new applications for the separators concerned. In the first of three surveys, conditioning by electrical means is considered. An account of the principles of electrically induced agglomeration is followed by a presentation and discussion of the possibilities and consequences of electrical effects applied to filtering separators, inertial separators, and wet separators. Wherever possible, points of practical relevance are also evaluated.     

40 Jahre Darstellung von Partikelgrößenverteilungen — und immer noch falsch?

While the quality and variety of particle size measuring instruments have improved dramatically in recent years, both in their accuracy and in their speed of measurement, the representation of the measured data — particularly the density distribution — has generally received little attention from the manufacturers. The depiction of a continuous density distribution by a percentage value on the ordinate makes no sense. Although logarithmic density distributions serve a purpose with distinctly separated bi‐ or multimodal distributions (by analogy with analytical chemical spectra), they can lead to serious interpretation errors in the case of the monomodal distribution. Thus for monomodal distributions either the density distribution q_r(x) should be used or no representation of the density distribution attempted.
