Comparing pulsing classifiers for waste-to-energy

Published

Journal Article

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. © ASCE.
