摘要：

In gas-solid two-phase flow, moisture in solid brings new challenge to the accurate measurement of solid concentration. A combined measurement method is proposed in this paper, which realizes the measurement of moisture and solid concentration in the gas-solid two-phase flow. The combined measurement is composed of capacitance measurement method and displacement-current phase (DCP) measurement method, which are both sensitive to moisture and solid concentration. The DCP measurement based on the principle of dielectric loss in measured field can share the same sensor with the capacitance measurement, which ensures the same measured section in the combined measurement method. Based on the combined measurement signal, the iterative decoupling method is adopted to realize the accurate measurement of moisture and solid concentration at same time, where the relationship between measurement and solid concentration for the expected moisture can be updated. The proposed method is verified by simulation experiments, where the results show that it can effectively obtain moisture and solid concentration in the gas-solid two-phase flow.
