METHOD AND BURNER APPARATUS FOR FLARING WASTE GASES

摘要

A method and flare burner apparatus for flaring inert vitiated waste gases in an efficient stable manner are provided. The apparatus is comprised of a first tubular member for discharging waste gases having an inlet end and a discharge end and a second tubular member positioned around at least the discharge end portion of the first tubular member whereby a discharge space is provided between the first and second tubular members around and adjacent the discharge end of the first tubular member. Burner means are disposed within the discharge space for discharging and igniting fuel gas therein and fuel gas conduit means are sealingly connected to the burner means for connecting the burner means to a source of fuel gas. Air conduit means are sealingly connected to the discharge space for connecting such space to a source of combustion air. Combustion air supplied to the discharge space is mixed with fuel gas supplied to and discharged from the burner means and the mixture is ignited and discharged from the discharge space and burned in a stable envelope around discharged waste gases. A portion of the waste gases are heated by the burning fuel gas and air, ignited and burned thereby providing a source of heat and ignition to the remaining gases which are burned in an efficient manner.
