Abstract
Field experience with air classifiers in waste‐to‐energy has indicated the need for redesign. Previous work indicates a heed to achieve separation based more on density and less on aerodynamic characteristics than is possible with current classifier technology. The development of the concept and theory of pulsed‐flow air classification are summarized. Methodology and equipment for testing various air classifiers are described. Laboratory experimentation shows that pulsed‐flow air classification is capable of superior separations by density than conventional classifiers. Comparisons with other types of air classifiers, including passive pulsing classifiers, show the active pulsed‐flow air classifier to be superior. Continuous‐feed comparison testing with a conventional zigzag classifier shows the superiority of the active pulsed‐flow system both in terms of separation efficiency and operational considerations, which are extensively discussed.
