Abstract:
Due to the worldwide problems with CO2 and reduced quantity of primary energy resources in the future, the plant-management in the metallurgical industry has to utilise the full energy potential of their plants.
In many of the pyro-metallurgical plants the utilisation of the process waste heat by means of heat-ing-usage, drying of process components or the recuperation of heat is limited. The power genera-tion from waste heat is probably one solution to avoid the loss of this energy and to save the global resources. In the new planned metallurgical plants and in many of the existing applications the primary process gas treatment downstream furnaces is done by waste heat boilers. These waste heat boilers produce steam at a middle pressure-level of 40 - 60 bar. The generated steam can be used for the power generation to improve the energy efficiency of the plant.
Oschatz designs and manufactures waste heat boilers for the metallurgical industry but also the industrial and municipal turn-key power stations for different wastes. The idea is to use this experience for the power generation in the non-ferrous industry.
The presentation describes existing furnace technologies with the corresponding waste heat boilers and shows the possible waste heat boiler concepts that could be realised in the non-ferrous industry. The main focus is to introduce the different possibilities of electrical energy production from the middle-pressure steam generated by the waste heat boilers. The presentation will give a preview for improvements and further developments which could be possible.
