Abstract
An ejector for providing motive gas for conveying particulate solids from a solids supply vessel through a conveying pipeline includes a gas introduction stage and a solids introduction stage. The gas introduction stage includes a fluids mixing chamber having a principal inlet port for connecting to a source of high-pressure compressed gas, an outlet port connected to the solids introduction stage, and a secondary inlet port that is open to the atmosphere or other low-pressure gas source. The solids introduction stage includes a fluids/solids mixing chamber having an, inlet port connected to the gas introduction stage, an outlet port for connecting to a pipeline, and a material receiving port for connecting to a vessel outlet. As the compressed gas enters the gas introduction stage, the high velocity gas induces atmospheric air or other low-pressure gas from the secondary inlet port, thus increasing the mass flow into the solids introduction stage.
