Pollution management with techno-economical evaluation for coke based and cokeless furnaces concerning melting and casting of brass and bell metal

India is a very important global player in the casting sector not only of cast iron but also of non-ferrous sector such as brass and bell metal. Melting furnaces of these are mainly coke based. There is also a growing awareness of pollution control levels in the country in recent times and this is a perceived as a threat to the existence of these small scale foundries including melting unit for casting for brass and bell metals scattered in various parts of the country. Attempt has been made to carry out research and development work on developing various modules eco-friendly furnaces concerning melting and of brass and bell metal casting/ product. This paper also discusses technoeconomical aspect of the mentioned coke based and coke less furnaces concerning brass and bell metal product
