ULTIMATE PERFORMANCE

COMPACT FLAME HIGH HEAT RELEASE

The LEx system generates compact, high intensity flames, reducing process influence on the combustion system performance.

HOW IT WORKS

The LEx uses a method of lean premix combustion and a controlled reaction zone to achieve ultra low NOx and CO operation. NOx emissions from premix combustion decrease rapidly as the amount of excess air is increased. LEx burners use this method to provide ultra low NOx emissions. See Fig. 1 The LEx burner establishes a lean premix and then combusts the mixture in a controlled reaction zone. The fuel and air are introduced separately into the burner where they are intimately mixed within the integrated mixers. This mixture is then directed into the reaction zone where the lean combustion takes place.
