According to finite element segmentation principle , by combining test with observation , the author has measured the air streamline and speed distribution of burning equipment in dally situation , which provides some guide for research of air field in hearth on cold and hot conditions . and the law is found of air speed distribution by measuring its speed and distribution of upper and lower deck on cold condition , thus it lays the foundation for analysis on hot condition . under four burning states , we measure the air speed in single , double - deck , and find out its corresponding distribution law 5 .根据有限元分割原理布置测点,采用降温方法,用k五江9106等仪器分别测出单双炉排燃烧方式4种不同工况下,该燃烧设备炉膛内coz 、 02 、 co气体浓度,并找到了随炉膛高度方向及深度方向变化规律;从燃烧原理分析评价了2种燃烧方式炉膛内coz 、 02 、 co气体浓度场分布特点及相应燃料层内干燥、干馏、氧化、还原、灰渣层厚度,肯定了双层炉排燃烧方式炉膛中c02 、 02 、 co气体浓度场分布合理性,从燃烧理论找出了最佳浓度场分布状态及燃料层内各反应层厚度。
If an anchorage connector installed adjacent to two branches each . the main pipe will expand & shrink in hot & cold conditions certically between the two floors . the distance between the supports shall not exceed 30m , other means can also be used to compensate , e . g . , install a expand branch pipe in the branch of the main pipe 如果主管的两个支管的附近各装锚接物,这样主支管就可以在两个楼板之间竖直产生膨胀或收缩,竖井中两个锚接点间的距离不能超过30米,也可以用其他的方法来补偿膨胀现象例如从主管的分管中装设“膨胀支管” 。
Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances . and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied . the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air , but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing 文摘:应用计算机模拟的方法,在不考虑燃烧的冷态情况下,研究了热风炉燃烧室内的气流分布规律.在此基础上,比较了2种不同设计方案的气流流动特征,尤其是研究了燃烧器空气通道内阻流板的设置与否对空气和煤气的流动和混合的影响.结果表明,阻流板的设计对加强空气和煤气的混合有着极为重要的作用,同时也增加了空气管道的阻力损失,在同样的工况条件下需要提高管道系统的总压力
