Heavy oil is indispensable in the process of copper smelting in a tilting copper melting furnace. In addition to reducing the temperature and saving oxidation time, the angle of the shaking furnace can also be improved. Determine the angle and timing of shaking the furnace during the oxidation stage, and program the shaking furnace into the operating program, which is highly efficient, can shorten the oxidation time by 1~2h, and save 10% of heavy oil consumption. Secondly, transform the diluted oxygen. The tilting furnace combustion system adopts diluted oxygen combustion technology. After the transformation, the energy-saving effect is immediate, the thermal efficiency can be increased by 40%, and it can greatly save energy and reduce emissions. The carbon emissions and nitride emissions are reduced by 45% and 87% respectively, which greatly reduces the unit consumption of heavy oil, and the cost per ton of anode copper can be saved by about 14 $.

In addition to heavy oil, LPG liquefied petroleum gas is also indispensable as a reducing medium. Improving the utilization rate of LPG can also reduce consumption and improve efficiency. The nitrogen-doped reduction process technology of the tilting furnace can be improved, that is, a nitrogen-doped port is added between the air duct valve group and the flow control valve group, and a group of nitrogen control valve groups are added; during the reduction start-up process, the LPG flow valve opening is controlled to 15%, and the N? flow is controlled to 200m/h. When the furnace angle is tilted to 17.5°, the LPG flow is restored to the normal setting value of 700m/h, and the N? flow is closed, and the furnace body no longer emits black smoke; during the reduction process, the LPG flow should be reduced to 500~600m/h, the N? flow is controlled to 100~200m/h, and the total flow of LPG and N? is controlled to 700m/h; during the reduction end and tilting furnace process, the LPG and N? flows can be controlled to 450 and 250m?h respectively, and the furnace body no longer emits black smoke.

From the above perspectives, the consumption of heavy oil and LPG can be better saved, making the combustion process of the tilting copper melting furnace more efficient.
