EXPERIMENTAL INVESTIGATIONS, OF EFFECT OF OXYGEN ENRICHMENT OF PREHEATED AIR ON PERFORMANCE, SPECIFIC FUEL AND ENERGY CONSUMPTION OF LDO FIRED ROTARY FURNACE
Journal Title: International Journal of Physical and Social Sciences (IJPSS) - Year 2012, Vol 2, Issue 8
Abstract
This paper deals with Experimental Investigations of oxygen enrichment of preheated air in LDO-fired rotary furnace, for optimal specific fuel and energy consumption. Energy consumption is major problem being faced by the Indian ferrous foundries. “Bureau of Energy Efficiency, “The Energy Research Institute,” Govt. of India New Delhi & other International agencies has reported that energy consumption in Indian ferrous foundries is much more above the required limits and has to be drastically reduced. The author conducted experimental investigation on oxygen enrichment of preheated air in a self designed and developed 200 kg rotary furnace in an industry The specific fuel and energy consumption of furnace, (when operated under existing conditions, without oxygen enrichment of preheated air,) in melting only was 0.460liter/kg or 4110.45 kwh/tone and total 4172.00 kwh/tone. When operated with oxygen enrichment of preheated air, the specific fuel and energy consumption in melting only reduced to 0.260 liter/kg or 2667.00 kwh/tone and in total to2711.00 kwh/tone. The energy consumption in melting only is reduced by 35.12% and in total by 35.01%.
