The assessment and design of waste heat recovery technology from the sand drier process in the foundry

The work deals with a possible solution on heat recovery related to the sanddrier 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 programme. Further, possible technical solution and its economic evaluation are stated in the work.
