| 摘 要： | 风量的准确测量对大型电站锅炉的安全经济运行有着十分重要的意义。一般风量测量装置对测量装置前后的直管段有一定要求,当直管段不能满足要求时,只能考虑加装整流器来进行调整。该文对整流器的形式、截面形状、高度、长度等因素对整流效果的影响及整流器的阻力特性进行了试验研究。试验结果表明:同矩形栅格相比较,相同高度情况下,蜂窝状整流器有着更好的整流效果,不过矩形整流器具有制作和安装简单,坚固的优点;蜂窝状整流器高度越小,长度越长整流效果越好,不过相应的阻力系数也会增加。试验结果可以为整流器及其参数的选择提供参考依据。

| Abstract: | Accurate measurement of airflow plays an important role in safe and economic operation of large scale power plants. Enough upstream and downstream straight pipe is necessary for flow measurement, otherwise rectifier should be used. Test researches on efficiency and characteristic of resistance of rectifier parameters such as shape, height and length are carried out. Test results show that, compared with rectangle gridiron rectifier, honeycomb gridiron rectifier has a better rectify efficiency with the same height. The smaller height and larger length of the honeycomb gridiron rectifier can provide a better rectify efficiency and a higher resistance coefficient. The results can provide a reference on structure and parameter of rectifier. |
