Heatflam KDLE Series Low NOx Gas Burners
Rugged, nozzle-mix, medium-velocity burners designed for high-temperature applications requiring strict emission control and high efficiency. The KDLE series delivers state-of-the-art low NOx firing with minimal excess air, offering exceptional stability and mixing for oxidizers, kilns, process heaters, and waste incineration.
KDLE Series (High Capacity & Low Emissions)
Field-proven combustion systems available in sizes from 1-1/2” to 16”, engineered to combine application flexibility with rugged durability.
-
State-of-the-art Low NOx: Advanced mixing technology achieves low emissions with reduced excess air (typically 20–30% at high fire).
-
Broad Capacity Range: 0.54 – 75 MBtu/h across varying sizes.
-
High Turndown: Exceptional flexibility with turndown ratios as high as 20:1.
-
Fuel Versatility: Efficiently burns natural gas, propane, and other gaseous fuels.
-
High-Temperature Operation: Handles maximum chamber temperatures up to 2000°F; accepts preheated combustion air up to 660°F (max. 800°F on request).
-
Process Stability: Medium velocity exhaust provides excellent stirring and mixing within the furnace.
-
Rugged Construction: Reinforced refractory block and steel body designed for demanding industrial environments.
