摘要
四角切圆燃烧锅炉炉膛出口气流的残余旋转，是形成水平烟道两侧烟气温度偏差的主要原因之一。作者通过冷态模化试验，研究了RG670／140－10型锅炉残余旋转的成因，探讨了消除残余旋转的方祛，并提出了一个判定反吹风消旋能力的W判据，可作为消除残余旋转的综合性指标。
In Centrifug al Firing System, residual rotation of airflow at furnace outlet is one of main reasons for gas temp. difference between two sides of horizcntal gas duct.Based on cold state modei tests, this paper gives research on causes of residual rotation in RG670/140-10 type boiler and eliminating methods, and proposes W value as basis of judging the capability of eliminating residual rotation by reverse mowing air, which can be regarded as a comprehensive index for eliminating residual rotation.
