| Abstract | India is stands 6th position in the world in producing castings. Foundry is one of the highly emerging industries in India. This study focuses on cast iron foundry in particular. The energy consumption of cast iron foundry processes is discussed in detail by considering the energy and mass balance of different foundry processes. Furthermore, this study broadly identifies energy efficiency improvement opportunities in foundry. One of the energy efficiency improvement options is divided blast cupola (DBC) by replacing conventional type cupola furnace. This can better results in form of metal to coke ratio, melting rate and charge coke consumption. Percentage savings in DBC are 55 % in charge coke consumption. Simple payback period of DBC is one year and six months. Another efficiency improvement option analysed in this study is the design and cost savings using minimum energy network (pinch analysis). Different streams are selected according to the plant layout and temperatures of the processes. Cost savings of 117,919 INR and 748.7 kW energy savings achieved per month per 350 tons of castings. In conclusion this study shows that there is an overall cost savings of 220, 0000 per year on 4000 tons of casting production. |
