摘要
利用气固两相流流过弯管处作用在管壁上的离心力的变化与气固两相流流量之间的理论关系,针对电厂锅炉燃烧系统送粉管道进行了弯管法测量煤粉浓度的试验研究,得出了相应测量送粉管道中煤粉浓度的数学模型,然后对其进行了误差分析,最后提出了在线检测的实现方法和作用.
Based on the theoretical relationship between gas-solid flow's centrifugal force change on outside and inside of bend and gas -solid flowing rate, we have made experimental research about measuring coal powder concentration in pneumatic pipes of boiler's combustion system with bend mehod. Then we have obtained a mathetnatical model for measuring the coal powder concentratuion in pneumatic pipes, done the error analysis, and provided a method of on-line measurement and its function.
