North American reGen ® Gas Burners
Bulletin 4630
4630 reGen Burners are made up of line burner sections to fire low temperature applications where heat must be distributed uniformly over a large area.
— Drying paints, textiles, metal parts, ink, etc. — Recirculating core ovens. — Cooking, evaporating, heating, etc. in the food industry. Other Heating kettles; preheating metal bars, castings, etc.; glass lehrs and fire polishing. Direct fired air heating applications: reGen Burners are stable with up to 12"w.c. mixture pressure in air stream velocities as high as 2000 fpm. They can operate in ambient temperatures up to 400°F. Assemblies can fire in any direction, including down. Flames are short and sharp at correct air/gas ratio, longer and yellow-tipped with rich mixtures. An assembly lights reliably from a single pilot. See Page 2 for 4630 selection information.
A typical reGen Burner assembly, with sections selected and arranged to fit a specific duct cross section with "J" flame rod adapter on pilot section.

Drillings are different for the elbows in some larger sizes, but capacities per foot are the same. Mixture manifolds should not be larger than 4" pipe size because of flashback hazard.
