How the “Diamond Head” operates“Diamond Head”:clean gas combustion.CUENOD’s vast experience in the fieldof combustion combined with amethodical search for the bestprocesses has produced a highlyefficient range of burners.Low NOx gas combustion involvesinternal recirculation of the combustiongases. These gases are partially drawninto the base of the flame viatriangular-shaped openings at the tip ofthe combustion head.The gas injectors are placed in suchway that a large quantity of combustiongas is drawn in and rapidly mixed withthe air and the gas at the root of theflame. This mix crosses the mainreaction area and slows down thecombustion, thus reducing thetemperature.The advantage of this technique is thatit automatically adjusts the amount ofrecirculated combustion gas: the flamealways has the most reliable volumewhich has little affect on the nominaloutput of the generator, unlike externalrecirculation systems.Burners C.260 to C.1100 are equippedwith “Diamond” low NOx class IIIcombustion heads, guaranteeingemission values compliant withEuropean Standard EN 676.An O2 regulation system (optional) canbe used to control excess air.This staged combustion system(IME ® system) leads to a significantdecrease in thermal nitrogen oxide.
