Applications Thermoprocessing

The efficiency and cost-effectiveness of thermoprocesses have two essential aspects. On the one hand, in addition to the purchase price of a furnace system, the operating costs arising from energy consumption, rising prices for CO2 emissions, and component wear are often decisive. Equally important, however, are product quality and reject rates, for which the temperature curves and interactions of the material to be heated with gaseous or solid components during the processes are decisive. At Fraunhofer-Center HTL, both aspects are taken into account to enable sustainable thermoprocesses. To this end, detailed, validated material models, digital twins for furnace systems and thermoprocesses, as well as high-temperature sensor technology and other high-temperature components are being developed.

Kiln Simulation and Digital Twins

The advancing digitalisation in industry also opens up fascinating opportunities for more efficient operation and faster development of furnace systems and high-temperature processes for thermoprocess technology. The simulation methods available today make it possible to use furnace simulations of varying detail, from simple thermal balances to complex coupled models of entire industrial furnaces, for reliable forecasts of operating conditions and the expected result of heat treatment.

Process Optimisation

Sustainable heating processes are a focus of research and development activities at the HTL. This includes issues such as the conversion of thermal processes to CO2-neutral operation, for example by using green hydrogen as a heat source, or the general switch from gas firing to electric heating. In addition to these approaches, which are usually accompanied by investment requirements for the user, the HTL also offers a systematic methodology for optimising thermoprocesses that does not require any structural changes to existing thermoprocess plants.

Sensors and Kiln Analysis

In the field of thermoprocessing technology, it is a particular challenge to obtain reliable measurement data from inside the oven due to the high temperatures, often in combination with aggressive atmospheres.
