Forge Ventilation help? Answered
Due to location & noise, in order to continue using my coke forge and anvil I must move indoors, into the shed to be precise.
I know it sounds a bit crazy attempting to run a coke forge in quite a confined (10-14 m3), fairly air tight space, but I have researched thoroughly the dangers and safe working levels etc and have the use of a fully calibrated gas analyser designed to measure CO in real time, so safe operation will be measured to the nearest ppm :)
The fans gumf claims 1060 m3/hr which I guess is best case, flat out @ 50hz and obviously does not allow for any other mechanical losses, but even a conservative estimate must give around 45 air changes an hour, which to me sounds like more than adequate clean air coming in to displace combustion gasses.
But I guess the first question is will the chimney work as a passive exhaust, to maintain positive pressure behind the chimney (which will be 12") I will have only a forced air inlet and no other vents other than the chimney itself, trouble is I can see it both working and not working:
1. Inside air will be forced up the chimney as that is the only way out = more ventilation
2.Inside air will cool the air in the chimney reducing the natural draw = less ventilation
And even if the CO issue is overcome will heat just ruin my plans anyway?
