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.<br>
