Hello Everyone,

I would like to thank everyone for their quick response and
suggestions.  Things appear to be OK at the moment (i.e., no more
column deaths) so I suspect that we had a batch of bad columns that
couldn't survive the cooling to standby (800°C) or cooling to room
temperature for ash removal.  To help prevent future problems and
speed up ash removal I will start to use the liners as many of you
suggested.

Thanks again,
Jennifer
