A Perception of an Eco friendly Furnace for Environmental Conservation in Foundry Industries

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, suspended particles, dust and grit have not been found within the pollution control limit as set down by central pollution control board of India. Therefore all the foundries in Taj Trapezium Zone (TTZ) have been ordered to be closed down by a recent order of the Honourable Supreme Court of India. It is not only the problem of India but is a global one. As per instructions of Hon'ble Supreme Court of India the cleaner technology should be used instead of cupola furnace. The author conducted a series of experimental investigations on the rotary furnace, installed at industries at Agra. These experimental investigations on the rotary furnace revealed that by reducing rpm from 2 to 1 not only the fuel consumption and emission levels were drastically reduced but its performance was also significantly improved
