Plant Optimisation Saves Energy
Can the coating dry more quickly? Is it possible to reduce the rejection rate? Does the plant use too much energy? Many companies ask themselves questions like these. Energy and material costs are important considerations for industrial companies who wish to maintain or improve their competitiveness. At the same time, the optimisation of existing plant can often be the more sensible and cost-effective option over installing new plant. A newly established consulting team at Heraeus Noblelight now offers support through individual consultancy, practical planning and prompt implementation of measures to achieve optimisation of plant, equipment and processes.
You can find optimisation potential best directly at the plant(firmenpresse) - A drying oven is often the bottleneck in a production line. In order to increase production output, a convection oven can, for example, be extended – but this is not possible in every factory. It is more efficient to replace the hot air with infrared heating or to use a combination of the two technologies, which can generally lead to savings in space and energy. However, the best way is to examine the complete system. “Recently, we have carried out detailed investigations of their system technology for one of our customers using Time-Distance diagrams,” explains Joerg Woell from the new consulting division at Heraeus Noblelight. “In doing so, we could see immediately that a conversion of the drying process would make sense.” This showed that by using fast-acting carbon infrared emitters, with electronic linking to the conveyor system, there is an optimisation of the operating life and significant energy saving. Precise calculations showed that following the conversion only 460 kW of power was required compared with the previous 880 kW.
To carry out such calculations, the new Heraeus division also used modern numerical methods such as Ray Tracing and Computational Fluid Dynamic, in addition to the usual tests in the Application Centre and the information contained in the data banks built up over years.
Identifying and Implementing Optimisation Opportunities.
The new consulting team provides consultancy and advice, planning and implementation of economical energy efficiency measures. In accordance with VDI 3922, Heraeus investigates production plants for potential improvements, using a practical approach which is independent of equipment manufacturers. Tests have been carried out for many years to analyse heating processes in our in-house Application Centre and on site. Experimental data in our databases, built up over decades, has also been useful for first assessments. Now we have added modern numerical techniques. Ray Tracing and Computational Fluid Dynamics are very valuable methods, for example, for optimising the homogeneity of heating on surfaces or minimising edge zone losses.
The use of modern infrared technology together with defined process optimisation increases the degree of utilisation of the production plant. It is important to understand the heating process precisely so that infrared heat can be used “on demand”. For example, if emitters are switched on only when a product to be heated actually requires heat, then energy is saved, operating life is optimised and efficiency is increased significantly.
“In the aforementioned case, we could not only achieve 60% energy savings but also a reduction in rework rate,” enthused Joerg Woell. The measures established are evaluated in terms of economic viability to illustrate the possible energy-saving and production opportunities.
