| Abstract: |
| Under the background of “Dual Carbon Goal”, China''s copper smelting, as a high-energy-consuming and high-emission industry, needs to break through the multiple constraints of resources, energy, supply and demand, in order to move towards the low-carbon, green, innovative and sustainable development of the copper industry. Adopting the energy flow balance model of the smelting system to study its energy income and expenditure situation is helpful to further explore the energy saving potential and realize the low-carbon sustainable and efficient production of oxygen-enriched bottom-blowing smelting process. By calculating the various types of heat income or expenditure behavior of bottom-blowing smelting system in copper smelters, the heat balance relationships without carbon-free fuel input were analyzed, and the optimization and improvement plan of carbon-free self-heating process was proposed. Therefore, in order to realize oxygen-rich bottom-blown carbon-free self-heating smelting, it can be controlled in many ways, such as raw material adaptation, operation system and equipment optimization. To reduce or avoid the addition of pulverized coal from carbon source, so as to reduce the carbon emission of the process, as a result, it can provide useful ideas and suggestions for the cleaner production of copper smelting. |
