Flameless Oxidation (FLOX)


With FLOX burners, the combustion gas and combustion air flow unmixed into the combustion chamber at a high flow rate. The gases are shot into the burner so quickly that the flames are blown away and a stable flame front cannot develop. The main difference to conventional burners is the very strong internal recirculation of the exhaust gases in the combustion chamber and their mixing with the combustion air. Due to this and the delayed mixing of air and fuel gas, a flame front can no longer develop. At sufficiently high temperatures of at approx. 800¬įC, the fuel oxidizes in the entire combustion chamber volume. This results in very homogeneous temperatures. The formation of thermal nitrogen oxides, which mainly takes place at the flame limit with its high peak temperatures, is avoided.


  • The fuel consumption is significantly reduced by the high combustion efficiency
  • The even temperature distribution in the combustion chamber reduces the thermal and mechanical load on the combustion chamber and can therefore considerably increase its service life.
  • Thanks to the low nitrogen oxide emissions, the emission limit values can be complied with without any additional denitrification system

The FLOX technology is an invention and product of WS Wärmeprozesstechnik GmbH (www.flox.com)
