FLOX

The FLOX procedure is a technical combustion processes without flame formation.

History

The possibility of a flameless oxidation ( FLOX abbreviated ) was developed by Joachim Alfred Wünning, the nephew of Joachim Wünning, discovered in April 1990 for tests on industrial burners. In his company WS Wärmeprozesstechnik the method was further developed and brought to market. The development has been promoted by a third party due to the specific advantages of FLOX method. Among other things, a pilot plant for the flameless combustion of pulverized coal has been developed in the research project " FloxCoal " the University of Stuttgart.

Technology

When FLOX process incoming gas burns flameless off from a temperature of 850 ° C. The gases are injected as fast in the burner that the flame be blown away and can not form a stable flame front. By a high exhaust gas recirculation is effected, that the substances related to the flame border can not form high temperature locally, whereby the maximum temperature occurring in the combustion chamber is reduced.

An outstanding effect for that build technology is the fact that the formation of nitrogen oxides (NOx ) drops to zero theoretically, as these develop at the flame front. In the currently implemented in practice, process the NOx emission decreased in Rhenish lignite by 20 % in Polish coal by 65%. During the renovation of existing burner systems with Thyssen -Krupp, the fuel demand could be reduced by 20 to 50 percent beyond.

With this technology, the company WS Wärmeprozesstechnik GmbH Joachim Alfred Wünning was honored along with his son Joachim Georg Wünning of German President Christian Wulff, the German Environmental Award 2011.
