Hi- I'm new to the forum- great place! This is my first post here. I didn't see this topic in the FAQ but maybe it is buried in this forum somewhere. If so, sorry for a repetitious post. I have a question about some Red Oak we have been burning here. Oak is a good fuel, of course, but what if it has a lot of deadwood on its surface? We had a large tree about 100 years old die after about 15 tough years. It eventually succumbed to insects and other disease. Neighbors built next door to us 20 years ago and excavated 4-5 feet below grade for a driveway, taking out at least a quarter of the root system. We're left with about 15 years of growth rings which turned from a blackish color originally to now a soft, rotten, sometimes crumbly white trash wood (2 years after being cut down). It is mostly healthy red wood except for this outer layer on many of the splits. My question is: will this produce a lot of creosote where normally I wouldn't expect to see much from such a good hardwood? It is a lot of work to trim off the bad wood from splits if this is unnecessary. I have done a lot of this with a hatchet. Can be done but is pretty darned tedious. I suspect the bad wood would have little BTU value in it, but my only major concern is the potential added creosote risk.
