Abstract This invention relates to outdoor refuse burning containers and more particularly to such containers incorporating a hood for improved filtration of burned products, for ordinary outdoor refuse burning barrels. A conical hood for such a barrel is provided, the hood being disposed over the barrel in a lift-off relation; and having a combustion product discharging vent with a removable filter cartridge inserted therein. The cartridge is pervious to escape of the burn products and presents an extended cartridge length through which these incineration products must pass to escape from the chamber. The combustion products are forced to pass first through the walls of a generally cylindrical cartridge, formed of thin sheets of expanded metal, and then through the interior of the cartridge which comprises a second labyrinthine path constituted of strips of expanded metal stuffed into the interior of the cartridge.
A removable smoke filter cartridge for a waste incineration chamber cover with an emission vent therein, comprising: a frame member removably engaged through said vent interceptingly of emission therethrough, and interiorly of said incineration chamber; and a filtration medium of strips of expanded metal coiled into randomly serpentine orientation and stuffed into said frame; said frame being positioned to permit emission of incineration products by flow through saiD filtration medium and said emission vent.
