An improved smoke suppressant apparatus for flare gas combination comprising a flare housing and a liner cylinder member coaxially disposed therewithin, an annular orifice channel formed between the liner cylinder and the flare housing. A first flare conduit is in fluid communication with the orifice channel and a first flare gas portion passing through the flare conduit is discharged from the orifice channel at the upper end of the flare housing as a perimeter zone discharge configured as a relatively thin cylindrical layer of flare gas. A second flare conduit may be provided in fluid communication with the inner core of the liner cylinder to discharge a second flare gas portion therethrough as an inner zone discharge, and a liquid seal is provided to permit flare gas to pass via the second flare conduit only when the pressure of the inlet flare gas exceeds a predetermined value. A fluid injected assembly is disposed within the upper end portion of the liner cylinder member for discharging a pressurized fluid into the perimeter zone discharge. A second fluid injector assembly may also be disposed around the upper end portion of the flare housing for discharging a pressurized fluid into the perimeter zone discharge.
