Abstract: A waste gas incinerator for burning waste gases is disclosed. The incinerator ensures substantially complete combustion of toxic and odoriferous compounds under high wind conditions, erratic flow rates and low ambient temperatures. The incinerator comprises an upright refractory liner generally cylindrical casing forming a heat sink, and has an open upper end and a lower end. An upper wind shroud is provided adjacent the open upper end and a lower wind shroud adjacent the lower end, both wind shrouds have a generally cylindrical shape with a larger diameter than the casing and a plurality of openings spaced around the wind shrouds. Air access is provided at the lower end of the casing, the access having a restrictor to limit air entry and cause turbulent air flow in the casing, and a waste gas entry to the casing.
