Process Heat

Industrial process heat and process gases are responsible for a significant proportion of the energy consumed by industry and commerce, but at the same time they have considerable potential as a source of energy for the same sector.


Around 40 % of industrial end energy is consumed by industrial furnaces. Although increases in the efficiency of a number of furnace types has helped to reduce specific energy requirements in the last few years, the energy savings potential here is still great and must continue to be exploited. A contribution is made by precision measuring techniques which assist the process control system, helping to increase both product quality and the production volume.
Process gases are the by-product of a number of industrial production processes and can be used for thermal energy. The energy content of industrial process gases is equivalent to one sixth of the natural gas consumed in Germany, and can therefore be considered a significant energy reservoir. Development activities in Germany are targeted at the efficient thermal utilisation of these process gases.
