- 1. Solar integration
No solar plant has been built yet. The first step was to find possibilities for heat-recovery and energy efficiency.
- 2. Industry Sector
(Surface) treatment of metals
- 3. Industrial application
Solar application: water heating for the black-finishing baths and maybe for heating the production halls
- 4. Process description

- Processes:
Black finishing:
- 5. Energy flows and temperature ranges
- Main heat supply system and fuel:
- Main fuels: oil & electrical energy
- Total electrical energy consumption: 80.000 – 100.000 kWh/a Electrical power: 250 – 270 kW
- Total oil consumption: 103 litres/day 2006: 38.205 litres, heating value: 10 kWh/l fuel heat capacity: 382.050 kWh

Description:
The solar energy is used for direct after-heating of the black-finishing baths, because water-baths at low- and middle-temperature levels are ideal for integrating solar process heat. To integrate such a system, the plant engineering would have to be changed.
- Performance of the planned solar plant:
A solar plant for providing the required 21.000 kWh with 30% solar ratio has to have an area of 20 m² and will produce 7000 kWh/a. These numbers are not calculated, but are only experience-data.
- Pictures of the built solar system:
No information available.
- 7. Energy savings
- Pinch analysis results:
No information is available.
- Energy savings:
No information is available.
- 8. Economic evaluation
- Economic parameters of the built solar system:
Investing costs: ~ 10.000 € Promotion: 30%
