Effect of Excess air on Emission level and Energy consumption of L.D.O. fired Rotary Furnace
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2012, Vol 2, Issue 5
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, H2 S, NOx, SPM etc. which damages the environment and are dangerous to all living beings. The emissions level of above have not been found within the pollution control limit as set down by Central Pollution Control Board of India. Energy consumption is another major problem being faced by the Indian ferrous foundries “Bureau of Energy Efficiency, and “The Energy Research Institute,”Govt of India New Delhi & other International agencies reported that energy consumption in Indian ferrous foundries is much more above the required limits and has to be drastically reduced. The authors conducted a series of experimental investigations on the L.D.O. fired rotary furnace installed at foundries of Agra and investigated the effect of excess air on Emission level and Energy consumption of Furnace. The experimental investigations revealed that by reducing excess air, not only the emission levels and energy consumption were drastically reduced but the performance of furnace was also considerably improved.
