建立了煤粉及焦炭燃烧火焰光束在回旋区内部的传输过程模型，提出了基于直吹管窥视孔方向CCD靶面热流分布的辐射传热方程（RTE）的蒙特卡洛（Monte Carlo）求解方法，分析影响回旋区三维温度场重建的辐射传递因子的影响因素。以及回旋区不同焦炭粒子浓度下回旋区的三维温度场重构问题，为实现回旋区工况的在线监测诊断提供了有效手段。

英文摘要：

We developed a process model of flame beam transmission using pulverized coal powder and coke combustion in a raceway. We employed a Monte Carlo computation method equation based on charge couple devrce（CCD） target heat flow distribution for radiation heat transfer. We explored the factors impacting radiation transmission. Based on these, a three dimensional reconstruction was analyzed at varying coke particle concentrations. This model provided an effective method to produce on-line monitoring of raceway working states.
