D / LND Series

Industrial Combustion D Series Burner

D series burners are performance proven in boiler, heater, furnace, kiln and dryer applications worldwide. The standard D series offers natural gas, propane gas, air atomized #2-#6 oil and combination gas/oil fuel options at capacities from 4,200,000 to 42,000,000 MBTU/Hour. The low NOx D series offers natural gas, propane gas, air atomized #2-#6 oil, and combination gas/oil fuel options at capacities from 3.4 to 42.0 MMBTU/Hour. A true forced draft design provides the ability to deliver rated capacities against furnace pressures up to 4" W.C.
