Dear stovers,
I have a few questions:
Does water at boiling have 1561 J/g energy? That is 4.186 J/C/g starting
at -273 deg C (0 deg K).and going to + 100 deg C?
If you need an additional 2260 J/g after the water reaches 100 deg C to
bring it to a boil that is like bringing the temperature to (2260 /
4.186) 540 deg. C but water does not go above 100 deg C (?). How is this
energy stored until it builds up to boiling point? Where is it?
If measuring the temperature along a very tall stack is there a place
where the temperature drops to 100 deg C (but still has the +2260 J/g
energy) and the water condenses releasing the +2260 J/g so the
temperature goes up?
If the fire under Lannys stove is of the size that before the heat
exits it is reduced (fins and length) to below 100 deg C. will the
released heat be included in heating the water and we should go by the
HHV and not the LHV of the wood? And is this a goal of producing the
'perfect' stove?
Thanks again,
Frank
