摘要
为了提高劣质煤燃烧稳定性，利用三维ＬＤＡ测量了稳燃腔燃烧器回流区三维速度分布及湍流度分布，在单火嘴试验台上进行了燃烧试验，并在２２０ｔ／ｈ燃用劣质无烟煤锅炉上投入实际应用。燃烧试验和实际应用结果都表明，稳燃腔燃烧器对提高劣质煤燃烧稳定性具有很好效果。
Abstract In order to improve combustion stability of low grade coal, the threedimensional velocity and turbulence distribution in the back flow region wasmeasured with a three dimensional LDA.Combustion tests were conducted in asingle nozzle test rig and actually applied in a 220t/h boiler firing low gradebituminous coal.Test and application results show that burners with stabilizingchambers are efficacious in improving combustion stability of low grade coal
