Effect of Moisture, Combined Water, and Volatile Elements on Fixed Carbon Requirement in a Ferro-Manganese Smelting Furnace
The effect of moisture, chemically combined water, and volatile elements in raw materials on the fixed carbon requirement have been studied by both experimental work and process modeling. Results show that the free moisture and combined water in manganese ores would not get much chance to reach the lower part of a ferromanganese fumace to consume carbon unless the residence time of a fraction of the solid charge in the upper part of the' furnace is much less than 1.8 hours. On the other hand, the volatile elements, especially the potassium, had a significant effect on the fixed carbon requirement due to their recirculation inside the furnace.
