I have posted the btu ratings using surface area vs stove body temperature but have yet to calculate btu's based on fire pot size.
It would be interesting to measure the coal usage of a Glenwood # 6 at full output during a 24 hour period during a cold night. And then we could extrapolate the btu rating and develop a breakdown for potential stove buyers.
At one point I knew the fire box dimensions for a Quaker # 8. Possibly 20 inches?
I think the most I've been able to push through my Glenwood over a 24 hour period is in the neighborhood of 100 pounds of coal. I recall a conversation on here some time ago where someone had said they could put either 125 or 150 pounds of coal through their stove so I tried to see what I could do. It was quite cold out and I'm not sure I made the 24 hour period running full out as it got very toasty in my house... But I guess the max amount of coal you could push through the Glenwood #6 would be close to 100 pounds a day if you need to use that for some kind of guesstimate of max BTU output. Although 75 pounds would be more reasonable to consider a throughput over say a week or more..
