Gas Burners

Dunphy industrial gas burners can be used with all types of gases, such as:

  • Natural gas
  • LPG
  • Hydrogen
  • Biogas
  • Coke Oven gas
  • Towns Gas
  • Syngas

These can be burnt individually, as dual gas burners, triple gas burners and simultaneously fired gas burners, where two or more gases can be burnt at the same time. The range is suitable for use on all makes and types of gas heat, steam and incineration boilers, furnaces and for process applications.

Gas burner variants are available in the range of 60kW to 80MW.

Low NOx combustion heads will reduce NOx emissions to 60mg/Nm³ and variable speed drives (inverters) and digital modulation can be fitted to provide valuable energy savings, with turndown ratios up to 10:1.

NOx levels less than 30mg/Nm³ can be achieved using flue gas recirculation (FGR).


The standard axial air flow burner, on designs up to 13MW, comprises a robust, cast aluminium housing. The motor is located within the air flow, offering 100% heat recovery from the motor and excellent acoustic attenuation.


A duobloc burner comprises a separate fan and motor and is standard on burners above 13MW or bespoke applications above 60kW ranging all the way up to 80MW. The duobloc burner is used for preheated air, incineration, ducted air, foul air, sluice gate utility burners.
