摘要：

Experiments of high-pressure dense-phase pneumatic conveying of different kinds of materials with different sizes were carried out. The conveying pressure was up to 3.0 MPa. The total pressure differential was up to 1.2 MPa. Effects of material categories, material properties and inclination angle on the resistance properties of inclined pipe were studied. Flow properties of experimental materials were measured by carrying out shear tests. Relationships between flow properties and resistance properties of inclined pipe were studied by combining the results of shear tests with pneumatic conveying experiments. Results show that the flowability of anthracite is better than that of petroleum coke with the same size. Pressure gradient through inclined pipe increases with increasing mass flow rate under the same superficial velocity. Pressure gradient through inclined pipe conveying coarse material is bigger than fine material of the same material. Pressure gradient through inclined pipe conveying petroleum coke is smaller than that for anthracite with the same particle size under the same operating parameter. Flowability contributes little to the difference in pressure gradient. Pressure gradient through inclined pipe increases with increasing inclination angle from 0° to 60°.
