Abstract
A process for the quiet and smokeless flaring of process gases by sharp separation of the air intake and combustion steps. Compared with conventional off-gas flares, steam consumption is reduced and blow-back of the flame into the mixing tube is avoided by using a combined mixing and combustion chamber. This extends the operating range and life of flare facilities.
