Fire without flame - sounds paradoxical and is at the same time a groundbreaking discovery. This combustion principle, which has a wide range of applications in numerous variants, particularly in the steel industry and in industrial burners for heat treatment, has unbeatable advantages. In contrast to conventional industrial burners, the sophisticated mixing of fuel gas, combustion air and recirculating exhaust gas in WS industrial burners avoids peak combustion temperatures in FLOX® operation. Thus, despite the use of high air preheating rates to significantly increase efficiency, the simultaneous increase in NOx emissions can be avoided. In addition, the homogeneous temperature distribution in the kiln ensures high-quality products and considerably reduced wear on the burners. These are all important factors for environmentally-oriented thinking, economic action and the production of high-quality products.

However, the potential of FLOX® technology is far from exhausted. In various national and international projects - some of which are supported by appropriate funding - the focus is on future fields of heat process and energy technology. For years, the focus has been on adapting our industrial burners to the special requirements of green fuels such as hydrogen, ammonia or methanol.
