[Stoves] Comments about T-LUDs

[Crispin Pemberton-Pigott]

Dear Andrew

This sounds right to me - I have been wondering all along why the TLUD is 
considered to be an IDD.  It is not really the same after all.  Micro 
currents of air/gas will definitely affect the way heat moves around the 
pellets (or elements) of the pyrolysis front.  It can't work exactly the 
same when inverted.  Your analysis looks spot on to me!

Thanks
Crispin
