摘要(Abstract)：

准东煤等高碱煤在新疆地区储量巨大，但其富含的碱金属元素极易导致炉膛受热面沾污、结渣等问题，会影响锅炉运行的安全性，研发高碱煤高效清洁燃烧发电技术对实现“双碳”目标有重要意义。总结了基于自发辐射分析的高碱煤燃烧炉内在线监测技术的研究进展，重点介绍了发射光谱技术、自发辐射图像处理及成像技术在高碱煤燃烧监测领域的研究现状及应用情况，进而对其发展趋势和动态进行探讨。发射光谱技术通过对火焰发出的不同波长光谱辐射信号进行处理获取温度与组分，近期，已广泛用于测量工业炉膛燃烧火焰温度和气相碱金属质量浓度，并基于此对炉内结渣趋势进行定性判断。自发辐射图像处理及成像技术具备信号空间分布的解析能力，利用CCD、CMOS等面阵传感器获取炉内自发辐射图像，基于图像处理与热辐射成像原理，结合辐射反问题求解方法，可以获得燃烧场在三维空间的温度分布以及二维壁温分布，使结渣的三维可视化监测成为可能。未来需基于发射光谱技术、自发辐射图像处理及成像技术对二维或者三维的受热面结渣沾污进行监测，结合炉内燃烧温度与气相碱金属质量浓度等参数分布，建立高碱煤燃烧受热面结渣沾污的定量判断指标，最终达到对受热面结渣沾污在线预测的目标。
