Flame temperatures of wood 1950 C ?
On the largest online chemistry textbook I found:
| Quote: | n daily life, the vast majority of flames one encounters are those of organic compounds including wood, wax, fat, common plastics, propane, and
gasoline. The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1950 °C. This is
because, in terms of stoichiometry, the combustion of an organic compound with n carbons involves breaking roughly 2n C–H bonds, n C–C bonds, and
1.5n O2 bonds to form roughly n CO2 molecules and n H2O molecules.

Well propane or natural gas in ideal circumstances I can understand. I sometimes melt cast iron using a propane furnace with air.
But wood ??? How can a woodfire reach 1900 C ?
By burning really dry wood with forced air, does it really get that hot ???

Didn't you just quote the explanation? Also:
"Note these are theoretical, not actual, flame temperatures produced by a flame that loses no heat. The closest will be the hottest part of a flame,
where the combustion reaction is most efficient."
We're not banging rocks together here. We know how to put a man back together.
