Berlie, E M; Smart, J D; Zelensky, M J

A waste gas incinerator for burning waste gases with additional fuel gas is disclosed. The incinerator uses the additional fuel more efficiently than other types of flares and can operate in high wind conditions. The incinerator comprises an upright refractory lined generally cylindrical casing forming a combustion chamber and heat sink, and has an open upper end and 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 has a restrictor to limit air entry and cause turbulent air flow in the casing. A fuel gas entry is located at the lower end of the casing, and a waste gas supply system within the casing has a preheater for preheating the waste gases with combustion of fuel gas and air, and causes turbulence of the waste gases. A waste gas entry is provided into the casing at a location where the fuel gas and air have commenced combustion.
