Michael,
for what it's worth, I rarely use firebrick above 1 foot above the roof
line of a Kiln. My reasoning is that by the time flame/heat has got that
far it has lost a lot of temperature, and therefore common red housebricks
at about 1/8th the price, and which over here are fired to around 1100 C -
2012 F, will suffice.
I haven't been proved wrong yet.
I also use perforated (10 holes per brick) red housebrick on the firebox
floor, the primary air comes in through them, and I hardly loose any of
them (except to over-enthusiastic stoking!).

Okay, I will take your info and get the lower cost bricks rated at 2000F.=

Somewhere way back I seem to remember that Fireplace Supply sold fiber
chimney liner you could buy in sections. Put up light weight galvanized
chimney pipe, and stack the 12 inch sections in the chimney and there
you have it. An easy built hightemp chimney not likely to burn out..
Seems like Mel also talked about this one time long ago as well.
