本文首先介绍了在切圆燃烧炉膛内燃烧器射流偏离方面的研究成果和提出的问题。然后根据对炉内流动工况的观测,提出了切圆燃烧炉膛内燃烧器射流的运动在本质上是属于横向气流射流的运动。根据这个流动模型推导出了射流在接触炉墙之前的运动方程,指出了影响燃烧器射流偏离的主要因素,并进行了试验验证。 This paper first introduces the research results and the problems raised in the burner jet deviation in the tangentially fired furnace. Then based on the observation of the furnace flow conditions, it is proposed that the movement of the burner jet in the tangentially fired furnace is essentially a movement of the transverse air jets. According to this flow model, the equations of motion of the jet before it contacts the furnace wall are deduced. The main factors that affect the jerk of the jet of the jet are pointed out and verified by experiments.
