NATURAL DRAFT LOW SWIRL BURNER

摘要

A new design for a low swirl burner is disclosed in which natural draft rather than a motorized pump is used to move a fuel-air mixture through the burner. This new design enables the burn off of gas at refineries in an environment where electric motors cannot be used because of the potential for sparks, which could trigger explosions. Additional modifications to the burner, including the introduction of flue gas to the burner allows for the reduction of NOx gas to meet current emission control targets, without the need for further post combustion emission control systems.
