| Abstract: | This paper deals with the solid discharge properties of a gas solid injector at different inlet suction vacuums and a fixed diffusor outlet pressureatmospheric pressure. Four particulate solids of 325 Mesh talc, FCC catalyst, coal ash and MBS resin are used to examine the effects of powder properties on solid discharge flow rates of the injector. The tests show that the solid/gas mass flow ratio varies linearly with the inlet suction vacuums and also differs in powder properties. |
