I would be afraid to use a draft inducer on an arch. Be certain it is designed to hold up to the temperatures the stack will have.
My arch , before air over fire (AOF) used to get to 1500-1600 at times, especially about mid point between fuelings.
My second concern is simply that I doubt it would improve the air flow enough to be worth it. I think you need a blower furnishing the combustion air and it should be able to be adjusted in intensity.
Besides, any draft inducer I'm aware of is to improve air flow in a forced air furnace heat duct, where the furnace blower has trouble getting enough heat thru a longer or undersized duct pipe. They typically have fans in the 1/70 -1/40 HP, hardly enough to help the fire burn. Get an appropriately sized squirrel cage blower and add an adjustable damper on the inlet to regulate

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.
