Duct Burner
(Duct Burner)
NBPKOREA Duct Burner generates infrared radiant heat from a surface combustion element made of heat-resistant metal fiber. Based on a technical partnership with MIDCO International (USA), it achieves low NOx and CO emission design compliant with ANSI Z83.4 / Z83.18 standards.
The NBP series lineup ranges from compact (0.5FT) to large (6FT), featuring a two-stage combustion method and 30-step precision turndown control for stable duct temperature management. Both LNG and LPG gas can be used without nozzle replacement.

Applications
Combustion Principle — Two-Stage Surface Combustion
Flame length maintained under 25cm / 30-step precision turndown control / Differential pressure 0.05"~1.4" W.C. wide-range operation
