Energy recovery in smelt furnace plants
In the industry that smelts metals, for example, the melting tanks are cooled by compressed air. The compressed air flows through cooling channels and absorbs heat. Normally, it is then released into the atmosphere without being used. With the new turbine generator, the compressed air, which is actually a waste product, can be reused profitably:
The energy absorbed from the heat can be converted into electricity by the micro expansion turbine and the integrated generator and then fed into the power grid.
