燃油浮法玻璃熔窑物理模型中喷枪位置的研究

Study of Burners Positions in Physical Model of Oil-firing Float Glass Furnace

根据相似准则,制作了燃油浮法玻璃熔窑物理模型以及可在不同位置上插入喷枪的3种小炉模型.将不同数量的喷枪放在小炉模型的不同位置,以常温空气模拟研究了实际燃油浮法玻璃熔窑中火焰空间内的气体流动状况.结果表明,喷枪安装在小炉底部时,炉膛内回流区的位置、回流气层的厚度较为适宜.同时还介绍了燃油喷嘴截面的设计情况以及模型制作方面的体会.

By similarity criteria an isothermal physical model of oil-firing float glass funace was set up to investigate the aerodynamics in the combustion chamber. The flow velocities in the model were measured by using three types of fire port with different burner positions and number of burners. The results show that the flow patterns and areas of recirculation are better when the burners are mounted under the port. Meanwhile the problems of model nozzle design and model making are discussed.
