Eco-friendly cokeless-cupola

Abstract

This paper envisages the developmental work on eco-friendly cokeless cupola at the National Metallurgical Laboratory, Jamshedpur. The normal Cupolas for melting cast-iron in major parts of the World are operating with coke as fuel and the emission from such cupolas have been found to he containing Suspended Particulate Material (SPM) in the range of 700 to 2500 mg/Nm3 with sulphur dioxide content of the order of 400-1000 mg/Nm3. From the pollution point of view, these figures are excessively high. The use of low sulphur gaseous/liquid fuel promises extremely low level of SPM and SOx and does not need any pollution control device and can very well be installed within any thickly populated municipal area. In view of the above, NML was entrusted by the Technology Information Forecasting and Assessment Council (TIFAC) of Department of Science & Technology (DST), Govt. of India, to design and develop a suitable eco-friendly cokeless cupola in order to provide indigenous technical know-how to the clusters of foundries located at various places in the Country.
