Abstract
The present application provides a back mixing device for use with a pneumatically conveyed flow of solids having a varying flow rate. The back mixing device may include a nozzle, a chamber in communication with the nozzle, and an exit. The chamber may include an expanded area leading to a restriction such that the chamber creates a recirculation pattern in the flow of solids so as to smooth the varying flow rate though the back mixing device.
Claims6
A pneumatic conveying system, comprising:
- a source of coal;
- a solids feeder in communication with and positioned downstream of the source of coal;
- a high pressure feed Vessel in communication with and positioned downstream of the solids feeder;
- a flow of conveying gas in communication with the high pressure feed vessel and a bypass line for bypassing the high pressure feed vessel;
- a flow meter in communication with and positioned downstream of the high pressure feed vessel;
- a first back mixing device in communication with and positioned between the high pressure feed vessel and the flow meter;
- a gasifier in communication with and positioned downstream of the flow meter, and
- a second back mixing device in communication with and positioned between the flow meter and the gasifier.
