摘要
通过测量圆形、月牙形孔板、文丘利管 3种阻力元件在气粉两相流中的阻力 ,分析 3种阻件的阻力系数 ξμ 与煤粉浓度 μ之间的关系 ,从比例阻力系数 Kj所受煤粉浓度 μ、节流比 m的影响程度上 ,来比较它们在用于测量煤粉浓度方面的性能 ,推荐使用文氏管测量煤粉浓度 ,并给出计算公式。图 9表 4参
The article analyses the relation between P.C(pulverizing coal) concentration μ and R.C(resistance coefficient) ξ μ of three different components with the investigation of their resistance in the gas solid phase flow. Comparing the degree that P.C. concentration μ and the throttle ratio m affect the resistance ratio coefficient K j , the conclusion is made that the ventures among three components is the best in performance measuring the P.C. concentration μ and the formula is recommended at the end of the text. Figs 9, tables 4 and refs 8.
