Possibilities of Energy Recovery and Integrated Energy Supply for Foundries

摘要

In many cases, the economy of industrial processes can be improved by energy recovery measures. Aim of this study was to investigate how far energy utilization in foundries equipped with electric melting furnaces and arc furnaces, in particular, can be made more efficient by means of heat recovery and integrated energy supply. Possibilities of waste heat recovery are derived from the energy flow sheets of arc furnaces with conventional refractory linings and with water-cooled linings and from from the temperature level of waste heat. Systems for heating service water, space heating in buildings, scrap pre-drying and support for steam generating plants are introduced.
