锅炉设计算法在火焰监测中的应用

Application of Boiler Designing Algorithm in Flame Detection

基于光纤光谱仪的光谱分析 ,火焰监测系统可实时监测锅炉火焰各特征区的平均温度和火焰黑度。在此基础上 ,笔者利用锅炉炉膛的一些设计参数和设计算法重新计算了炉膛出口烟气温度等参数 ,并简要介绍了数值模拟结果。最后讨论了炉膛出口烟气温度的新计算值的意义 ,结合实践提出了炉膛污染指数这一新概念。这为以后的工程设计提供了依据。

Flame detecting system based on fiber optic spectroscopy can monitor the temperature and optical density of boiler flame. As a further work, the temperature of fume is computed again ,which is at outlet of the chamber of furnace. Finally, the significance of new calculating result is discussed. This will provide reference for the engineering design.
