Abstract

An apparatus (having at least one burner having a plurality of co-axial channels and a control system for regulating a length of a flame for partial oxidation of hydrocarbon feed in a reactor is provided. The at least one burner has a first channel to inject a stream of oxidizer, a second channel to inject a stream of the hydrocarbon feed and a third channel to inject a stream of swirl gas at a first velocity into the hydrocarbon feed stream. The control system regulates the length of the flame to have a constant flame shape and position by regulating the first velocity of the swirl gas that generates the swirl motion within the hydrocarbon feed stream.
