1燃烧器介绍某电厂300 MW锅炉是采用美国燃烧工程公司ABB-CE的引进技术设计和制造的。锅炉采用四角布置的切向摆动式燃烧器,燃烧器采用水平浓淡煤粉燃烧技术,以提高锅炉低负荷运行的能力,水平浓淡煤粉燃烧器是利用煤粉入燃烧器一次风喷嘴体后,经百叶窗的分离作用,将一次风气流分成浓淡两部分;两部分之间用垂直隔板分开,燃烧器出口处设有带波纹形的稳燃钝体。浓相气流的煤粉浓度高着火特性
1 Burner Introduction A 300 MW boiler in a power plant is designed and manufactured using imported technology from ABB-CE, a U.S. combustion engineering company. The boiler adopts tangential oscillating burners arranged in four corners, and the burner adopts the horizontal rich and weak pulverized coal combustion technology to improve the capability of the boiler to operate under a low load. The horizontal rich and light pulverized coal burners use pulverized coal into a primary air nozzle body of a combustor, The separation effect of the shutter, a wind flow divided into two parts shades; between the two parts separated by a vertical partition, the burner outlet is provided with a stable smooth bluff body. Concentrated air flow pulverized coal concentration high ignition characteristics
