PrimeFire 400 Oxygen Fuel Burners Feature Flat-Frame Geometry
The Low NOx PrimeFire 400 is a nozzle-mixing burner featuring flat-flame geometry. This flat-flame shape provides enhanced flame coverage and uniform heat distribution, resulting in improved product quality and extended furnace refractory life. Specifically, the advanced design of the PrimeFire 400 incorporates a pre-combustor at the back of the burner. This pre-combustor mixes a portion of the combustion oxygen with the fuel stream, causing gas cracking which produces free carbon particles that increase luminosity and improve the radiant heat transfer to the glass load. As a result, overall furnace efficiency is improved, peak flame temperatures are reduced, and NOx formation is lowered.
