Ultra-Low NOx Technology with Temperature Uniformity Benefits for Forge and Heat Treat Applications

Fives North American Combustion’s Diffuse Mode Combustion (DMC) is a patented flameless technology that can achieve ultra-low NOx emissions and improve temperature uniformity in forge and heat treat applications.  DMC technology applied to the industry standard Tempest® burner builds upon proven heat patterns and furnace performance, while reducing NOx emissions to ultra-low levels in furnaces operating from 1500 to 2300°F. By allowing fuel and air to combust in a dilute, volumetric basis within the furnace, rather than the burner tile, the maximum flame temperature is reduced and the point source of radiant energy normally present in the flame is smoothed out, improving temperature uniformity.  

The Tempest® DMC product can operate at an extremely wide range of air/fuel ratios, from 30% excess fuel to 2000% excess air.  The product is also capable of StepFire™ in order to maximize fuel savings if desired.

Results of ongoing research and development work and initial beta site testing will be presented.
