Abstract
Apparatus for enhancing combustion of an undesired chemical to minimize the formation of smoke during operation of a flare stack for the discharge of a flare feedstream includes a plurality of high-pressure air nozzles spaced apart below and around the periphery of the stack outlet. Each nozzle is directed toward the stack outlet and in the direction of the feedstream's movement. High-pressure air from the nozzles forms a plurality of high-velocity air jets to produce a moving air mass that draws additional atmospheric air into the air mass moving toward the stack outlet to enhance combustion of the flare feedstream. Analytical means determine the stoichiometric oxygen requirements, and an air-flow valve controls the flow rate of the high-pressure air to the nozzles. Air flow control means adjust the mass flow-rate of high-pressure air based on minimum oxygen requirements determined by the analytical means, whereby the oxygen content of the air flow at the stack outlet meets or exceeds the requirement for the complete combustion of the feedstream.
