[Gasification] grate design

[Peter Singfield]

Regarding refractory linings -- gates -- 

Maybe you can get a few ideas by simply reviewing the in place -- working
technology -- presented at this Url:

And contact Kevin to get one to play with.

These are filtered and gas cooling units.

the stochiometrics for my project.

lot of different fire bricks, I'm left wondering if the temperature limits
of that material is high enough.  As far as the thickness and motion of the
brick, I would assume that the motion helps to move the char down and that
affects the bridging that may occur otherwise.  The thickness then affects
the residence time as the fuel progresses down.  Have you experimented with
different thickness?  A recently asked question was about injecting steam
into that section.  Have you ever tried anything like that?  I'm sure that
the amount of steam will significantly affect everything.

castable liquids, the higher temp ceramics are relatively solid and
somewhat dry.  They are easily formed by hand like one is making a clay
pot, adding only enough water to work it without cracking.  I'm soon to
find out and not scared to make a mistake at this point.
