BSR.002 — District heating and combined heat and power in combination — The running time of the CHP is sustainably increased
2021-04-08
Initial situation
The new DHL mega parcel center in Bochum was built on the former Opel factory site. The parcel center has its own combined heat and power plant for supplying electricity and heat to the parcel center. However, the property not only receives electricity or heat, but also feeds the heat produced in the cogeneration plant into the network of the Bochum municipal utility.
The company ewers supplied two large special district heating transfer stations for this purpose. One station with 1,500 kW supplies the 34,000 m2 hall and the 4-story office building with an area of 2,700 m2 with heat from the district heating network of Stadtwerke Bochum.
The second station, with 700 kW, feeds the surplus heat generated in the company’s own CHP unit back into the Bochum district heating network.
If you have any questions, please do not hesitate to contact us.
