Karim Zahedi, Jeffrey C Alexander: Filter apparatus and method for collecting fly ash and fine dust. EFB, Shapiro and Shapiro, December 29, 1981: US04308036 (47 worldwide citation)

Fly ash and fine dust in a gas stream from a coal combustor, for example, are efficiently collected in a 2-stage, tubular, granular bed filter. The stages of the filter are arranged one above the other so that the granules may move from the upper stage to the lower stage under the influence of gravi ...
