To more uniformly distribute heat to the plurality of catalyst tubes in a catalytic reaction furnace, the burner disposed in the furnace above the tops of the tubes includes concentric primary and secondary annular fuel and air outlets. The fuel-air mixture from the primary outlet is directed towards the tubes adjacent the furnace wall, and the burning secondary fuel-air mixture is directed horizontally from the secondary outlet and a portion thereof is deflected downwardly by a slotted baffle toward the tubes in the center of the furnace while the remaining portion passes through the slotted baffle to another baffle disposed radially outwardly therefrom which deflects it downwardly in the vicinity of the tubes between those in the center and those near the wall of the furnace.

Catalytic reactor with improved burner

This invention relates to means for minimizing the smoke emitted from the exhaust of a gas turbine engine by judiciously adding air to the primary burning zone of a combustor at discrete locations. This invention contemplates retrofitting existing burners by substituting the improvement for existing can burner components to obviate the necessity of replacing the entire combustor.
