The targets set for CO2 savings and the reduction of NOx emissions at a well-known automobile manufacturer were achieved by using WS burners with ceramic finned recuperators in gas-fired pusher-type furnaces.
Rexnord Kette GmbH and WS have successfully modernized a belt furnace, reducing the furnace's CO2 emissions by 35%. In addition to new burners with maximum energy efficiency, the optimization of the operating mode also contributes to the CO2 reduction.
Thanks to patented gap-flow technology, REKUMAT® S NT burners achieve the highest energy efficiency with the lowest emissions even at low furnace chamber temperatures below 600 °C.
The patented REKUMAT® CR burners allow for the first time the substoichiometric operation of a recuperative burner due to the integrated afterburner. Highest efficiency and lowest NOx emissions thanks to FLOX® technology.
REKUMAT® M series: Energy-efficient recuperative burners for radiant tubes and direct heating. Thanks to FLOX® with extremely low NOx emissions and ready for operation with green hydrogen.
Energy-efficient recuperative burner for indirect and direct heating applications. Revolutionary gap-flow technology for highest possible efficiency.
The new research field of thermal process technology is dedicated to the goal of defossilizing high-temperature processes above 1,000 °C. While some processes are flexible enough to be heated with renewable electricity, climate-neutral fuels will be necessary for many applications in the future.
The targets set for CO2 savings and the reduction of NOx emissions at a well-known automobile manufacturer were achieved by using WS burners with ceramic finned recuperators in gas-fired pusher-type furnaces.
WS has been known worldwide for decades as the undisputed technology and market leader in the field of industrial burner technology for the thermoprocessing industry. For next-generation products, state-of-the-art manufacturing processes such as additive manufacturing are of course also used.
The WS Group was blessed with beautiful weather on April 30, 2025 when almost 500 guests accepted the invitation to "Dance into May" to celebrate the inauguration of two newly built halls in Renningen. With a large number of employees, customers, suppliers and political guests, the day was an entertaining experience that included in-depth technical discussions as well as joint networking.
