首先介绍了在切圆燃烧炉膛内燃烧器流偏转方面的研究现状 ,然后根据对炉内流动工况的观测 ,提出切圆燃烧炉膛内燃烧器射流的运动在本质上是横向气流射流的运动 ,在分析这个流动模型的卷吸及所受作用基础上推导出射流偏转的计算方法 ,并针对典型 6 0 0 MW的炉膛进行了计算及试验验证 .计算及实验验证表明 ,这一方法可以成功地预测四角切圆燃烧炉膛内燃烧器射流的偏转和实际切圆大小 ,对切圆燃烧器的设计有一定的指导意义 First of all, the research status of burner flow deflection in tangentially fired furnace is introduced. Based on the observation of the flow conditions in the furnace, it is proposed that the movement of the burner jet in the tangentially fired furnace is essentially the movement of the transverse jet, Based on the analysis of the entrainment and the effect of this flow model, the calculation method of jet deflection is deduced, and the calculation and experimental verification of a typical 600 MW furnace are carried out. The calculation and experimental verification show that this method can successfully Prediction of the deflection and the actual tangent of the jet of the burner in the tangential firing furnace have some guiding significance for the design of the tangent burner
