| 摘 要： | 常规水平浓淡燃烧器的双通道速度差达6～8 m/s,该速度差会对燃烧稳定性、燃烧效率和NOX排放造成影响,通过对常规直流煤粉燃烧器、水平浓淡煤粉燃烧器和等速型低NOX燃烧器在350 MW电站锅炉上的燃烧过程数值模拟表明:浓淡燃烧技术不改变锅炉炉内的传热特性,等速型低NOX燃烧器比水平浓淡燃烧器可降低NOX排放12%.

| Abstract: | The velocity difference of air in two channels of the conventional dense-dilute pulverized-coal concentration burner is 6-8 m/s,which impacts combustion stabilization,burning efficiency,and NOX emission.The process of combustion in a 350 MW boiler was simulated and the results showed that the dense-dilute pulverized-coal concentration combustion technology did not change furnace radiation heat transfer,and NOX emission of low NOX pulverized-coal burner in same velocity of two channels was 12% lower than tha... |
