Abstract

A system for removing pollutants from gases in which one or more beds of activated char are formed in a housing having an upper chamber and a lower chamber. A first series of beds of activated char extend through both the lower chamber and the upper chamber and an additional series of beds of activated char are disposed only in the lower chamber. A system of passages and baffles are provided in the housing to direct the gases in the upper chamber through the first series of beds of activated char, and the gases in the lower chamber through the first series of beds of activated char and then through the additional beds of activated char, before the gases exit from the housing.
