Dear Prasad,

You could lower the draft. Possibly some kind of injection like steam or
engine exhaust.

One possibility would be to run in a slagging mode. In other words keep
the slag at a high temperature so that it is in a liquid state until it
is out of harms way. But that might not be possible with a down draft.



NOT an expert,


Jeff
