Waste Heat Recovery Technology from the Sand Drier Process in the Cupola Foundry

摘要

The work deals with a possible solution on heat recovery related to the sand-drier SCH 5 in a foundry. The heat recovery applied on air entering the heating chamber is designed in this variant. The work consists of analysis of drying process including balance calculations, design with relevant calculations, including possible power savings, the way of control of the relevant foundry sand drier, used at present and possibility of visualization of the control system by means of Control Web program. Further, possible technical solution and its economic evaluation are stated in the work.
