[TheForge] coal forge exhaust system

[Paul N]

Has anyone on the list tried using one of these (or similar) ducted exhaust systems for a coal forge?

I'm finally setting up a permanent shop, and was hoping not to have to run a stack high up above my roof ridge line. If I can run a forced exhaust system out my gable wall, I can save some money, as well as avoid having a tall stack on the roof.

These things are all for sale all over the place, with some pretty significant CFM numbers. I'm concerned about the temperature as well as the volume of air moved. I don't think I need a whole lot of static pressure, but I do want to be able to exhaust coal fumes without starting the place on fire.

Thanks,
