摘要

针对燃烧室氮氧化物排放量高的问题,本研究对工业机器结构进行了优化,以提高燃烧性能。分析结果表明,烟气再循环(FGR)可有效降低燃烧温度和机膛内高温区的分布,从而在不影响机膛内气体速度的情况下抑制氮氧化物的形成。在仿真分析的基础上,将 FGR 技术应用于改造机器结构,并评估了实际应用中的改造效果。结果发现,加入 FGR 后,炉子出口处的氧气含量从 13.8% 降至 10.5%,炉子的氮氧化物排放量从 80 mg/m3 降至 18 mg/m3,天然气消耗量减少了 17% 以上。这些结果表明,在优化设备结构后,节能减排效果显著,可为后续该领域的研究人员提供参考依据。

Industrial equipment optimization for combustion performance enhancement: a real-world case study
To address the issue of high NOx emission from the combustion chamber, this work optimized the industrial machine structure to enhance the combustion performance. The analysis results indicated that the flue gas recirculation (FGR) could effectively reduce the combustion temperature and the distribution of high-temperature regions in the machine chamber, thereby suppressing NOx formation without affecting the gas velocity inside the chamber. Based on the simulation analysis, the FGR technology was applied to modifying the machine structure and evaluated the modification effect in real-world application. It is found that after adding FGR, the oxygen content at the furnace outlet decreased from 13.8% to 10.5%, the NOx emission from the furnace decreased from 80 mg/m3 to 18 mg/m3, and the natural gas consumption decreased by more than 17%. These results demonstrate a significant impact on energy saving and emission reduction after optimizing the machine structure, which can provide a reference basis for subsequent researchers in this field.
