摘要
在总结前人关于煤粉燃烧方面的利用技术的基础上提出了撞击流技术 ,并分析了撞击流技术在强化煤粉燃烧上的原因。利用 Powell提出的“镜象”模型 ,结合实际煤粉燃烧炉 ,借助有限单元法对撞击流的流场特性给予了数值模拟。最后 ,介绍了实际工业利用实例 。
Based on summarizing of existing utilizing technologies of coal powder combustion, impinging stream technology was put forward, and the cause of impinging stream technology in reinforcement of coal powder combustion was analyzed Using'mirror image' model made by Powell and combining the real coal powder combustion stove.Utilizing finite element method,the digital-analogy of flow field characteristics of impinging stream was carried out.Finally,the real industry utilization was introduced example and application of this technology was forecasted.
