Air Requirements for Coal Combustion

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

My basement is roughly 15ft x 15ft x 7ft cube = 1575 cubic feet..

SO if this is all correct then my furnace uses one full volume of the basement in combustion air every 5 and half hours..

And that doesn't count what the baro is sucking up the chimney which I would think is grossly more than combustion. :lol:
....the amount of air turnover...by volume...in most of our homes is pretty staggering- most ppl don't believe the math

When you're heating your house most of the mass you're heating is the house itself - walls, floors, etc., - not the air in it. It doesn't take a lot of BTU's to heat just the air, so some amount of turnover of air is not a big problem. If anything, turnover of air is needed to maintain the quality of the air in the house.

I totally agree...

but some ppl just cant believe how much "air " the average home turnsover in a day....even when you show them !

EXAMPLE: in Lightnings scenario above... the typical electric household CLOTHES DRYER would evacuate his basement in about 11 minutes....as compared to his stove ( 5 1/2 hrs)
