I'm new to using coal, so I've been lurking here reading up on it as much as I can, and I think I've got a pretty good grasp of things. (Just enough to be dangerous?)
A little info...
I have a Round Oak coal furnace in my workshop. I don't know the model, but it's a 72,760 BTU, 535 CU.IN. unit with a squirrel cage blower on the back and duct openings on top. It came from a house in northern Missouri that was built in 1910, but I don't know if it was installed then or added later.
I brought it back here to central Oklahoma to heat my workshop. I've been burning wood in it for the last several years but thought I'd try using coal, mainly so I can keep my workshop above freezing at night without having to add wood every two hours. I started searching the web for info on coal, went and bought a ton from a local mine, and thought I was all ready to go. BUT, I have one major concern...
Will the fly ash destroy my galvanized metal building?
It's an all metal building similar to these.http://www.futurebuildings.com/future-s ... dings.html
I thought about switching to coal if I liked it because that's what the furnace is designed for, or just using the coal during the night and wood during the day. But I saw this post and now I'm afraid to even try using the coal at all.http://nepacrossroads.com/post129121.html#p129121
How many of y'all have metal roofs or workshops, and what kind of rust or corrosion problems have you had?
Thanks for the info!
