An Innovative Technological Experimental investigations of an Eco friendly Furnace for Environmental Conservation in Foundry Industries

ABSTRACT The large amount of flue gases produced by cast iron foundries using Coke fired cupolas for melting, contains injurious elements like SO2, CO2, CO, H2S, NOx, SPM etc. which damages the environment and are dangerous to all living beings. The emissions of SO2, CO2, CO, H2S, SPM, dust and grit have not been found within the pollution control limit as set down by central pollution control board of India. As per instructions of Hon’ble Supreme Court of India the cleaner technology should be used instead of cupola furnace. The series of experimental investigations were carried out on a 200 kg rotary furnace installed in foundry shop in an industry. The rotational speed RPM was gradually reduced from 2 RPM and it is concluded that optimal RPM is 1for reducing emission level as per norms of CPCB Central pollution control board of India.
