<p>The present work aims to modify the laboratory-scale indigenously fabricated transferred arc plasma furnace design by changing the different parameters to enhance energy consumption, meltdown time, electrode, and graphite consumption performance.

摘要

The present work aims to modify the laboratory-scale indigenously fabricated transferred arc plasma furnace design by changing the different parameters to enhance energy consumption, meltdown time, electrode, and graphite consumption performance. The steady-state heat loss was calculated considering the design parameter reported in earlier literature. After identifying the possible scope of design and operating parameters’ improvement, the furnace was prepared with the modified design. The prepared furnace was characterized by heat loss, meltdown time, energy consumption, graphite electrode consumption, and magnesite lining erosion. The result shows that the furnace made with a modified design decreases heat loss by 44.76%. The energy consumption (MJ/h) decreases by 3.23% with a decreased average meltdown time of 05 min/kg of metal. It also decreases 20% graphite electrode consumption (kg/min) and 17.74% magnesite lining erosion (kg/min), respectively. In summary, this study presents a remodified prototype transferred arc plasma furnace that offers improved functionality and efficiency compared to the previous design. These modifications are expected to address the challenges of high heat loss during furnace operation and improve the overall performance of the furnace.
