	<span style=\"line-height:1.5;font-size:14px;\">随着闪速炉的投料量及精矿中杂质含量升高，烟尘在流经相关设备时容易粘结，造成排烟系统不畅，降低了闪速炉作业率，直接影响闪速炉的正常安全运行。研究发现排烟系统故障的原因为烟气中金属氧化物易吸附形成粘结，造成通烟困难以及烟气中废酸酸度高，会加剧排烟系统腐蚀，降低设备使用寿命。通过应用在线烟气分析系统，调整锅炉结构，改进现有除灰装置，更改电源发生器等一系列优化与改进手段，解决了闪速熔炼排烟系统中烟尘易粘结及烟气腐蚀性的重要难题，保证了排烟畅通和余热锅炉运行安全，提高了闪速熔炼的生产效率，增加了经济效益。<br />
With the increase of feed rate of flash furnace and the content of impurities in concentrate, soot is easy to bond when flowing through relevant equipment, resulting in poor smoke exhaust system, reducing the operating rate of flash furnace and directly affecting the normal and safe operation of flash furnace. The study found that the cause of the exhaust system failure is that the metal oxide in the flue gas is easily adsorbed to form a bond, which causes difficulty in passing smoke and high acidity of waste acid in the flue gas, which will aggravate the corrosion of the smoke exhaust system and reduce the service life of the equipment. Through the application of online flue gas analysis system, adjustment of boiler structure, improvement of existing ash removal equipment, modi-fication of power generators and other optimization and improvement methods, it solves the problem of easy adhesion of smoke and corrosion of flue gas in flash smelting and exhausting sys-tem, guarantee smooth smoke exhaust and safe operation of waste heat boiler, improve the pro-duction efficiency of flash smelting and increase the economic benefits.</span>
