Today I burned a bunch of long dead branches that may have had some moisture from rains a week or two ago. I burnt them in a holey barrel to heat water for the redneck hot tub. The coil ended up coated with some crusty tarry stuff. Never has before with eucalyptus firewood and a more open setup. An open bottom drum set up on rocks. I wonder if the moisture and cooler metal of the coil caused stuff to adhere to it?
Maybe certain burning conditions in a stove (like a gasifier) and a cool stovepipe or chimney cause “condensation” of vapors?
