为改善由于四角喷燃锅炉残余旋转引起的水平烟道速度分布不均匀的状况，介绍了一种将分隔屏偏置的新方法。试验表明，将分隔屏组合偏置，效果最佳，可使水平烟道内速度不均匀系数下降达８５％ 。将分隔屏分别偏置３０°、４５°和６０°，水平烟道内速度不均匀系数可下降３０ ％ 左右。因此表明文中提出的方法是可行的，它为提高大型机组火电厂运行的安全和经济水平，防止超温爆管事故的发生提供了一种新的措施。
In order to improve the uneven horizontal flue velocity distribution caused by the residual rotation of the four-corner combustion boiler, a new method of biasing the partition screen is introduced. Experiments show that the combination of the partition screen bias, the best results, the horizontal flue can reduce the velocity non-uniform coefficient of 85%. Separating the separating screens by 30 °, 45 ° and 60 ° respectively, the non-uniform coefficient of velocity in horizontal flue can be reduced by about 30%. Therefore, the method proposed in this paper is feasible. It provides a new measure to improve the safety and economy of large-scale unit thermal power plant and prevent the occurrence of super-temperature squib.
