Unless you are just curious, don't worry about it's flame temperature. Just give it all the oxygen it needs and keep adding wood according to a timer. I've burned everything from Bass wood, to oak, cedar, cherry, locust, ash, sugar maple, pine and hemlock plus many others. While each species may need a longer or shorter refuelling interval, they all boiled just as well as any others, you just need to figure out the time for adding more. On mine, once I added AOF (air over fire) has been 8 minutes on the softer woods to 9 if all harder woods. Just make sure it's dry and split to wrist size in at least 1 dimension and not over 2x wrist size in the other.

Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
