Description
Auto-translated from GermanStadtwerke Flensburg GmbH operates a heating plant at the property Batteriestraße 48 in 24939 Flensburg for the generation of electricity and district heating. The heat storage tank 2 was commissioned at this site in 2024. It is available to the district heating supply of the city of Flensburg as a buffer storage with a capacity of approx. 29,000 m3 of treated district heating water. Originally, this heat storage tank was integrated in parallel with heat storage tank 1, which has been in operation at the heating plant site for approx. 50 years. After the commissioning of heat storage tank 2, a condition assessment of heat storage tank 1 was carried out, which showed that a renovation is not economically feasible. For this reason, heat storage tank 1 is currently being dismantled and will be replaced as planned by the new heat storage tank 3 to be erected at the same location. Heat storage tank 3 is to be constructed as a non-pressurized heat storage tank with a steam cushion, identical to heat storage tank 2 already operated at the site. This means that a heat storage capacity of min. 900 MWh with a maximum storage temperature of 98 °C and a return temperature of 65 °C (Delta T 33°C), and furthermore a maximum charging and discharging capacity of 90 MW, is to be realized. The estimated dimensions of the storage tank are an inner diameter of approx. 42 m and a maximum filling height of approx. 21 m. Due to the parallel integration with heat storage tank 2, the same geodetic height of the maximum fill level must be achieved for both tanks in any case. The scope of supply and services includes in particular: Planning and production of the foundation slab for the heat storage tank, see also 00_ProjectDescription
