Waste Heat Recovery



Heat loads coming from an industrial site at different flow rates and temperatures have to be transferred to a heating grid. Since there is much more heat available than demand for district heating, the excess heat originally would have to be cooled down. The hot water return temperature to the industrial site has to remain the same at all time.


Our client, an energy supply company in Germany, operates a heating grid close to a large industrial site.



We installed an INDUCAL NT300 ORC-unit.

With a smart heat management system that is installed on the same skid as the ORC unit always the optimal amount of energy is sent to the heating grid then to the ORC-unit and last if needed, to cooling directly. This way the INTEC GMK ORC-system always optimizes automatically the electricity and heat production while maintaining a steady hot water return temperature.

After the heat management system conducted the right amont of water flow towards the ORC-unit, the heat is efficiently transformed into electricity. The ORC- and heat management system operate from 10% up to 300% of the rated heat load continuously.
