摘要
针对一种新型电站锅炉使用的高风温直接点火的煤粉燃烧器,在现场实验和数学模型的基础上详细讨论了煤粉浓度、煤粉气流速度、热风速度和温度等因素对煤粉气流着火的影响规律,为燃烧器的设计与运行参数的选择提供指导。
Focusing on a new kind of pulverized coal burners in power plant boilers for directly ignition with hot air, based on on-site experiments and mathematical models, the effect of the coal powder＇s concentration, the pulverized coal entraining air＇s velocity and temperature, on ignition of a coal powder stream is being discussed in detail to serve as a guidance for burner design and also for the proper choice of operational parameters. Figs 10, tables 2 and refs 2.
