D/LND Series 2018-04-26T11:33:00+00:00

D/LND – Series

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 and #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.

Capacities and Specifications


Lower gas supply pressure configurations available for New York City requirements

  • Firing rates based on altitudes to 2000ft. above sea level.
    * For firing rates at higher altitudes, consult factory.
  • Gas input based on natural gas at 1,000 Btu/cu.ft. and 0.60 gravity
  • Oil input based on 140,000 Btu/gal. on D/LND, 145,000 Btu/gal. on DM and 150,000 Btu/gal. on DE series.
  • Boiler overall efficiency of 80% estimated. Industrial Combustion does not guarantee overall boiler efficiency.
  • Furnace pressure and furnace dimensions and required NOx emissions may allow higher firing rates than shown above,
    consult factory
  • Motor horsepower based off of standard design backpressure rating.
    * Consult factory for review and comparison to your application.
  • Shipping weight is only an estimate
