ABSTRACT:
A gas conveying system capable of conveying a solid material without pushing or compressing the solid material. The system comprising: at least one conduit assembly comprising a conduit, a lance assembly disposed about a first end of the conduit which is capable of removing the solid material from a holding device, and a first eductor which is capable of entraining the solid material in a gas stream and moving the solid material through the conduit; a cyclone disposed about a second end of the conduit, the cyclone being capable of separating the solid material from the gas stream; and a second eductor disposed to receive the solid material from the cyclone, the second eductor being capable of entraining the solid material in a second gas stream which has a solid-material-to gas mass ratio which is greater than that of the first eductor. The second stage eductor transports the particles further downstream for storage, additional transport, or for further treatment, such as burning in an incinerator.
