In 2007, an indirectly heated roller hearth furnace with energy-efficient REKUMAT® burners was put into operation at a Schaeffler plant in Germany. These burners were serviced last fall in Renningen and adapted in order to be operated with both natural gas and H2 as fuel with high efficiency and lowest emissions. The successful commissioning with natural gas has already been carried out, and once the hydrogen infrastructure has been established, commissioning with H2 as fuel gas will proceed.
With this and other conversions as well as newly built projects, Schaeffler is demonstrating its comprehensive commitment to sustainability while investing in the long-term future of the respective plants. Wienstroth Wärmeprozesstechnik GmbH in building the plant and then servicing it recently helps with the adaptation to H2 as fuel. This conversion is possible for many existing plants with reasonable effort, without having to install new burners. Until the necessary hydrogen infrastructure is available, continued operation on natural gas or mixtures of natural gas and hydrogen is possible.
