摘 要: 采用计算流体力学(computational fluid dynamics, CFD)技术,对回转窑冷态流场进行数值模拟研究。模拟结果显示:在回转窑中产生中心回流区、内回流区和外回流区,与前人的研究情况相符,从而证明网格的合理性、数值方法的可靠性,以及现场燃烧器的优越性。所研究的四风道煤粉燃烧器性能良好,有助于提高水泥煅烧质量和效率。
关 键 词: 煤化学工程;回转窑;数值模拟;回流区

Abstract: In this paper, computational fluid dynamics (CFD) technology was used to study the cold flow field in the rotary kiln. The results showed that there were central reflux zone, internal reflux zone and external reflux zone in the rotary kiln, and was consistent with predecessor’s research, which accounted for the rationality of the grid, the reliability of numerical method and the advantages of the burner. The performance of four-channel coal burner was helpful to improve quality and efficiency cement calcination.
Key words: coal chemical engineering; rotary kiln; numerical simulation; reflux zone
