| 摘 要： | 在一维平面层流煤粉气流着火的数学模型的基础上,发展了一种更加逼近工程实际的一维平面紊流煤粉气流着火模型.在该数学模型的指导下,设计了高温空气煤粉点火试验台.通过大量的空气加热试验和煤粉气流着火试验,对模型进行了实验验证.结果显示,理论模型的计算结果与实验相符合,验证了高温空气煤粉点火技术的可行性.

| Abstract: | A more accurate one-dimensional turbulent ignition model of pulverized coal air flow in a tube was established on the basis of the one-dimensional plane laminar flow ignition model. An experimental plat for high temperature air pulverized coal ignition was set up. To test the theoretical model, air heating and pulverized coal ignition experiments were done. The experimental results are in good agreement with the calculated ones. The feasibility of pulverized coal ignition by high-temperature air was proved. |
