I am trying to find technical information about dust insufflation systems in kilns. I would like to know what technologies are available and who supplies them. I would also be interested in hearing stories about successes and difficulties in using this technology. Thank you.

Dust insufflation in kiln
Adrian
I believe that you run a wet kiln. From my experience I can tell you , there is not a complicated technology you need only a hopper, a dosing sistem,a pneumatic pump and a pipe(refractory steel). Important is the position of pipe in the kiln : -between burner and material bed, or opposite to this(in this position be carefull to avoid dust falling on ignition point of fuel).I don't recommend to insufflate dust through primary air or center of the burner. For dosing and conveyance of dust you can contact Claudius Peters.
There is also a possibility to introduce dust in the kiln through holes in the kiln shell after chains zone but at a more expensive investment.
Good luck!

Thank you for the information.
Do you, or anyone, know names of specific companies or plants where insufflation is currently being used?

Unfortunately I don't know names,but you can contact wet kiln plants to get some informations.Usually in U.S.A. contact manufacturers like Holcim,Lafarge,Cemex .
