电站锅炉煤粉燃烧器一次风煤粉气流火焰传播特性试验研究

Test Investigation on Primary Air Pulverized Coal Flow Flame Transmitting Characteristics of Power Utilities Boiler

采用煤燃烧试验室的专项试验装置和规范化的测试工艺，对包括无烟煤、烟煤和褐煤在内的五种动力用煤的煤粉气流火焰传播速度进行测试，试验结果表明：煤粉浓度、煤粒尺寸。

Using the standardized measuring process of special test device, pulverized coal flow flame transmitting velocity of five kinds of power coals including lignite, anthracite and bituminous coal etc. had been measured, the test results shows the pulverized coal concentration, coal particle size, original temperature of pulverized coal flow and coal property etc have difference influences on layer flow flame transmitting characteristics.
