摘　　要：采用标准k-ε湍流模型和近流线的数值模拟方法,对四角切圆燃烧锅炉炉内的空气动力场进行了数值研究,得到了实际一次风喷口出口两侧存在速度差对炉内空气动力场的影响情况,并与通常把一次风喷口出口速度均匀处理后数值模拟结果进行比较,其对比结果对于电厂的实际运行具有重要的参考价值。Using the standard k-ε model and uniform streamline simulation theory, a simulation is carried out to study the aerial dynamic field in a tangential firing boiler. The impact of the velocity difference between the right and left parts of the primary air nozzle on the aerial dynamic field in the tangential firing boiler is obtained. The study could serve as reference to the power plant operation. Figs14 and refs 7.
