Incineration system having cyclonic oxidation chamber

摘要

An incineration system includes a rotary drum incinerator unit having a primary oxidation chamber and a secondary oxidation chamber for receiving gases of combustion from said primary chamber. The secondary chamber has a plurality of coaxially arranged walls which define a torturous reversing spiral flow path for gases of combustion passing through said secondary chamber whereby to effect substantial retention time and cyclonic separation of particulate matter from the gases.
