Description:
The solar thermal plant feeds a puffer-store, which is connected to a process-water store via a heat-exchanger. Fresh water and the warm reflux from the processes are fed into the process-water store. The average mix temperature in the store is 39,8 °C. The water in the process-water store is then heated up to 60°C via the heat-exchanger and the solar thermal plant. Warm water with 60°C can be taken continuously from the store for the processes. If there is not enough solar radiation, the boiler is used for supplying enough heat.
- Performance of the simulated solar plant:
- Pictures of the built solar system:
No information available.
7. Energy savings
- Pinch analysis results:
No information is available.
- Energy savings:
Considering a total efficiency factor of 85 %, 110.200 kWh of gas would have to be provided, to get 93.700 kWh energy. The production of 93.700 kWh solar energy results in a saving of 3.527 €/year of fossil energy, if calculated with the present energy prices.
Energy balance for the processes: 477.709,03 kWh Energy saving potential with solar heat: 93.700 kWh
- 8. Economic evaluation
- Economic parameters of the built solar system:
The economic evaluation was done for a combination of energy saving concepts (heat insulation, bio mass boiler…), not only for the solar integration described.
