Waste Heat Boiler For Nonferrous Smelting Oxygen-Enriched Furnace
**Waste heat boiler for oxygen-enriched furnace for nonferrous smelting** is a system that uses the heat energy in the high-temperature exhaust gas generated by the oxygen-enriched furnace in the process of nonferrous metal smelting to convert it into useful energy (such as steam, hot water, power generation, etc.) through the waste heat boiler. Oxygen-enriched furnaces are widely used in the process of nonferrous metal smelting, especially in the smelting process of nonferrous metals such as copper, lead, and zinc. It can significantly increase the furnace temperature, improve the reaction efficiency, and reduce energy consumption. However, a large amount of high-temperature exhaust gas will also be generated. The application of waste heat boilers can efficiently recover the heat energy in these exhaust gases, thereby improving energy utilization efficiency and reducing environmental pollution.

Waste heat boilers for oxygen-enriched furnaces for nonferrous smelting are mainly used in the following nonferrous metal smelting processes:
- **Copper smelting**: In the copper smelting process, oxygen-enriched furnaces are often used to increase the furnace temperature and promote the reaction, but they also generate a large amount of exhaust gas. Waste heat boilers can effectively recover the heat in these exhaust gases for power generation or heating.
- **Lead smelting**: Oxygen-enriched furnaces are also often used in lead smelting. The temperature of the waste gas generated in this process is relatively high. The heat energy can be recovered through the waste heat boiler and used for heating, steam generation or power generation in the plant area.
