Abstract：Using pressure drop measurement and electrical capacitance tomography (ECT) methods, the flow pattern, pressure drop and pressure fluctuation characteristics of syphon and Venturi pipes were investigated.By effective pressure drop signal of Venturi pipe, statistical evaluation index was constructed to evaluate the powder flow stability.The results show that, pressure drop signals of Venturi is appropriate to evaluate the powder flow stability in different operation conditions.
