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 2,511,000 to 37,800,000 MBTU/Hour. A true forced draft design provides the ability to deliver rated capacities against furnace pressures up to 4" W.C.

Features Include:

  •   Low-pressure air atomizing system on oil with rotary vane   compressor
  •   Cam trim with 14-point adjustment range for consistent   air/fuel ratios
  •   Parallel positioning available for optimal control through out   the firing range
  •   Low NOx with FGR capabilities
  •   Piston-type positive displacement oil metering system
  •   Gas manifold on oil burners standard for easy upgrade to   combination units
  •   Hinged combustion head for easy access and maintenance
  •   Backward-curved impeller provides adequate combustion air   for various furnace pressures
  •   Nozzle line electric heater standard on medium to heavy oil   burners
  •   FGR modulating valve
  •   UL & cUL listed

Notes:

  •   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
