Callidus - Ultra-Blue Burner (CUBL) Brochure

The Callidus Ultra-Blue (CUBL) is rapidly becoming the preferred Ultra-low NOx process burner.

An innovative design has been employed which increases the burner’s stability and allows for optimal performance on typical refinery fuel gases and 100% natural gas. The new design also increases the tile exit velocity which enhances fuel/flue gas/air mixing, providing a shorter, “stiffer” flame as compared to other next generation Ultra-low NOx burner designs.
