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.
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
Capacities and Specifications
Notes:
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
