Andrew an road map; first question in heat transmission is surface, second temperature jump, third thermal coefficient transmission of material, and fourth is rugosity involved in heat conduction.

We found exactly the same problem 7 years ago when building our large 
wood dryer. So David Beedie sized everything from scratch using 
simple physics principles and the rule of thumb not to exceed 10 
metres/sec for any gas velocities. It was near enough right first 
time.

There are so many variables that it must be a black art, I spoke with 
the chap that oversaw the design of UK's first straw burning plant. 
He was ex navy and familiar with ship's steam turbines, so the 
design was similar but he says they had to make changes to the fire 
tubes and superheater on the fly during commissioning.
