Description
The original combustion investigations on the ASARCO Shaft Melting Furnace concept indicate that dissolved oxygen in the copper from the melting furnace was introduced at higher levels at lean and relatively rich combustion ratios in the premix in the shaft furnace burners. The original experiment was duplicated under several common combustion conditions on an operating shaft furnace to validate the original experiment and to indicate the optimum combustion ratios for the melting of copper for the production of rod.
