In most cases, the heat generated by industrial production processes is still released into the environment and thus into the atmosphere. If this waste heat were to be used on a large scale to generate electricity, this would make a significant contribution to climate protection and a sustainable energy industry. However, the temperatures of the waste heat generated by industrial plants depend on the respective industrial processes; they are usually between 100 and 500 degrees Celsius. The waste heat can therefore only be converted into electricity with the help of the Organic Rankine Cycle (ORC). In this process, an organic fluid with a low boiling point is used instead of water. In this way, turbines can be used efficiently to generate electricity even below 300 degrees Celsius.
Previous research work, in which the Center of Energy Technology (ZET) at the University of Bayreuth was involved, among others, has shown: When converting large amounts of industrial waste heat into electricity, a particularly high degree of efficiency is advantageous. The Nuremberg-based company TGM Kanis Turbinen GmbH now wants to apply the experience it has gained so far in steam applications to the development of a turbine with improved efficiency. The findings are to be transferred to the conversion of industrial waste heat in the new project, which is being funded by the Bavarian Ministry of Economic Affairs, Regional Development and Energy from the Bavarian Energy Research Programme. A corresponding ORC turbine is therefore to be built at the Nuremberg site. This is to be scalable up to a capacity of ten electrical megawatts (MWel).
The Center of Energy Technology (ZET) of the University of Bayreuth, which has extensive experience in operating geothermal ORC test plants on the Bayreuth campus, will support and drive the pilot project with its scientific expertise: It is responsible for the conception and design of the test stand, corresponding process simulations, and scientific monitoring of the plant's operation. A Bayreuth master's student from the Faculty of Engineering is also involved in the project from the outset. In his thesis, he will deal specifically with process simulation and the initial design of the plant. Further student work is already firmly scheduled.
