Processing metal with solar energy

03.11.2011
Solar-generated saturated steam fed into steam network at 140 °C

In Germany, industrial process heat comprises around 10% of the energy requirements. Part of it can be generated with solar thermal systems. Using twelve collectors that track the sun’s position, a metal processing company in Ennepetal, Germany, has for the first time generated saturated steam and integrated it into an existing steam network.

The pilot system is presented in the new BINE-Projektinfo brochure “The sunny side of saturated steam” (11/2011). In this research project, the process’s operational basis for utilising solar process heat was tested and optimised, whereby a particular focus was on the future use of such systems in more southern parts of the globe.

Saturated steam is steam produced at the saturation temperature and is used in many industrial production processes up to 200 °C. In the pilot system, steam is generated directly in the absorbers within the parabolic trough collectors, thus eliminating the need for a special heat exchanger. This improves the efficiency. A company in the aluminium-finishing sector has integrated the solar steam generator into its existing steam network. Here, the steam is used to quickly heat various chemical baths to temperatures between 60 and 110 °C. As expected, the solar yields from this pilot system were relatively low, which is partly due to the limited collector surface area. The project itself, however, was deemed to be successful because it enabled a highly promising process for generating and directly feeding solar steam to be realised and tested in long-term operation. The process could also be used in other sectors for drying and heating processes and for solar refrigeration.

In order to achieve temperatures above 100 °C with solar heat, concentrating collectors are deployed. The pilot system uses parabolic trough collectors – a technology in which German companies are among the best in the world. The BINE Projektinfo brochure “The sunny side of saturated steam” (11/2011), which can be obtained free of charge from the BINE Information Service at FIZ Karlsruhe, is available online at www.bine.info.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
