Marc,
Setting aside heat transfer to the pot, I was just wondering if the
reported gas temperature differences, with and with out the screen,
might represent a delta T across the screen ( about 90C) and then we
could look at the enthalpy change in the gas as a ball park check on
the radiant heat flux from the screen. Of course many assumptions must
be made about mass flow until excess air numbers are available but those
can be made reasonably to shed some light on the likely boundaries of
real stove conditions.

transfer that would give us useful quantitative results. There are
lots of messy quantities to deal with in that calculation (mass flow,
heat transfer coefficient, ...)
