摘要
为了研究低挥发分煤粉着火与火焰稳定性,分析了气相燃烧与煤粉燃烧的着火贫限,提出了低挥发分煤粉着火的一次风粉气分离原则.实验证明,根据这一原则设计的开缝纯体燃烧器对低挥发分煤粉的着火与火焰稳定具有较好的适应性.
For the purpose of investigating the ignition and flame stability of low volatile pulverized coal, an in-depth analysis has been made on the lean flammability limits of gas-phase and pulverized coal combustion. The principle of separation of air from dust for the ignition of low volatile pulverized coal with primary air is presented. Experiments show that a new-type pulverized coal burner with a slit bluff-body designed on the said principle is suitable for the ignition and flame stability of low volatile pulverized coal.
