Overview
Copper smelters are enterprises primarily engaged in the production of copper products. The primary and secondary energy and energy carrying working fluids consumed in the production process mainly include coal, heavy oil, light oil, liquefied petroleum gas, steam, oxygen, compressed air, water, etc. Energy consumption is mainly used in the smelting process. Among them, metallurgical furnaces are important energy consuming equipment. Therefore, improving the effective utilization rate of thermal energy in metallurgical furnaces. Reduce heat loss and maximize the recovery and utilization of waste heat resources. It is to strengthen enterprise energy management. Reduce energy consumption. One of the important measures to improve the energy utilization efficiency of enterprises. Due to technical and economic irrationality issues. Some of the waste heat resources are discarded. And most of them are recovered and reused through copper smelting waste heat boilers. The copper smelting waste heat boiler is one of the equipment in the copper smelting process, so the safe and reliable operation of the waste heat boiler is related to the normal operation of the entire process flow.

Working principle
Reasonably recovering its waste heat is a complex technology that involves the rationality and economy of waste heat utilization schemes. The commonly used recycling method is to install a waste heat boiler with an air heater. On the one hand, it uses flue gas to heat the anode furnace air supply (350 ℃), reducing the fuel or coal consumption of the anode furnace (increasing the anode furnace air supply by 100 ℃ can reduce the fuel rate by 4% to 5%, and the energy consumption of the anode furnace can be reduced by about 15%). On the other hand, the steam generated by the waste heat boiler is used for production and daily life, which can improve the utilization rate of waste heat.
The copper smelting system has a large amount of flue gas and high flue gas temperature. Using a copper smelting waste heat boiler to reduce the flue gas temperature (360-400 ℃) is beneficial for tail gas treatment (dust collection and acid production), while recovering the steam generated by waste heat for power generation and production. The use of copper smelting waste heat boilers to recover flue gas waste heat, with a remaining heat utilization rate of 45% to 80%, is currently the most commonly used method for waste heat recovery.
Performance characteristics
1. In response to the particularity of copper smelting process and the complexity of flue gas, our company's copper smelting waste heat boiler has successfully solved the problems of ash accumulation, wear, air leakage, ash removal, etc. that plague waste heat boilers;
2. It has good adaptability to exhaust gas temperature and exhaust gas dust;
3. Adopting a multi-layer protective board insulation structure with strong air tightness and simple structure;
4. The components are assembled at the factory, easy to install, and have a short cycle;
5. Strong self dust removal ability, effectively reducing the dust concentration in the flue gas discharged from the boiler, laying the foundation for environmentally friendly emissions of flue gas;
6. The exhaust temperature of the waste heat boiler is low, and the waste heat utilization efficiency is high.
