any idea why poplar would cause thick black smoke to come out of my owb?
if it was just moisture, wouldn't it be white? this is weird.. when I burn pine or oak or hickory, everything is nice and clean - just a puff of white smoke when the combustion cycle kicks back in. but with the poplar, it's dark and heavy.
the wood goes a long way though, and has no problems getting the water up to temp, despite the wood's low btu. I came into a huge free load of the stuff last year and have a pile to burn through, but I don't like doing so if it's going to continue to cause the dark smoke.
any ideas what would cause this?
