本文以数学模型为手段，研究了在不同空气预热温度、不同火焰长度下单辐时管壁温分布规律及烟气温度变化规律，同时研究了在不同参数下群辐射管性能变化的规律。获得了有实际指导意义的结论。
In this paper, the mathematical model is taken as a means to study the law of wall temperature distribution and the variation of flue gas temperature under different air preheating temperature and different flame length, and to study the law of group radiation tube performance under different parameters. Obtained practical guidance of the conclusions.
