| 摘 要： | 文提出了一种采用电容传感器测量气固两相流质量流量的新方法。通过电容传感器对固相浓度的测量,可以求出气固两相流的固气比,结合气固混合之前所测得的载气流量,便可测出固相的质量流量。实测结果显示,测量误差小于5

| Abstract: | A new method for the measurement of mass flowrate of gas solid two phase flow is presented in this paper. This method indicates with the measurement of solid phase concentration using capacitance transducer, the solid to gas mass loading ratio Z can be measured. Combining the gas mass flowrate measured before pulverized coal is inducted into pipe and the solid to gas mass loading ratio Z, the solid mass flowrate can be calculated easily. The results of practical measurement show that errors is less than 5%. |
