Utilization of waste heat in an foundry including feeding heat into a district heating network

A concept was developed to use the waste heat from the production of cylinder-liner which in detail could be feeded into the energy supply of the whole district. The usage of waste heat produced by cooling the induction oven as well as using the thermal energy from the cast-blanks after founding are realized in this Projekt. Due to the measures a large potential or thermal energy (about 2000 MWh/a) which otherwise would have been left unused can be used for the companie´s heating demand as well as to feed the heat into the district heating network (further information in German).
