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. The furnace models can be further developed into digital twins which, depending on their characteristics, can be used either for automated furnace control or targeted furnace and thermal process development. Fraunhofer-Center HTL is working with these methods in current projects and is continuously developing them further.

Digital Twins

A computer model of a production process and the equipment involved, which reproduces the real process so reliably that it can be used to determine the optimum process parameters, and which is in constant data exchange with the control system of the real kiln plant, is often referred to as a digital twin. In the case of reduced or no data exchange, one rather speaks of a digital shadow or simply a digital model.

Kiln Simulation

In industrial heat treatment processes, large-volume furnaces are usually used to maximise the throughput of the material to be heated. The heat is transferred from the heaters to the material to be heated by convection and thermal radiation in the furnace atmosphere, as well as by thermal conduction in the kiln furniture used and in the material to be heated itself.
