FLOX®  stands for  »FLameless OXidation « and describes a distributed reaction in the combustion chamber. It was discovered and further developed by Dr. Ing.J.A. Wünning.

 

The process can be utilized at temperatures above 850°C and therefore fits perfectly to steam reforming of natural gas.

Typical temperature field in a FLOX®-fired combustion chamber.

 

In contrast to a classical flame, which forms a highly intensive reaction zone at the burner mouth, fuel gas and air are injected this kind, that the reaction takes place downstream distributed in the combustion chamber. Ignition takes place only by recirculation of hot gases in the combustion chamber. This leads to extremely low NOx-emissions and allows stable operation even with low calorific gases.
