Process and assembly to optimize burner operating characteristics by re-circulation of gases through vortex generator to air inlet

摘要

A fuel (gas/liquid/dust) burner has a modified gas flow pattern. During the burner start-up phase combustion air (3) passes through a vortex generator (12) located within an air jet passage (7) with re-circulation passages (2). The re-circulating gases modify the pressure distribution within the air inlet.
