Does burning anthracite eliminate creosote from the flue?

Does burning anthracite eliminate creosote from the flue?

PostBy: italia899 On: Thu Apr 05, 2007 5:36 pm

A coal supplier stated that anthracite does do that. Is there any truth to that? I know burning anthracite does not produce creosote. I would like to know this because next fall I plan on burning wood on warmer days then switch over to anthracite when the temps dip into the low 40's.

Thanks

I am no expert, actually I am a coal virgin. but I don't see how burning coal will remove the creosote unless you are running really high stack temps. Just my thoughts, maybe an expert will post some actual findings.

Antracite does not produce any creosote. It does give off a little flyash, which amounts to a very fine ash similar to cigarretes. It will over time remove the creosote from clay tiles, you'll find a pile of black dust at the cleanout after the season. I have no idea if it will do the same with a steel stack but would assume so.

Yes it does. I did this for many years. It will clean the chimney out quite nicely, if you burn it long enough. I used to have a terrible problem with creosote in my chimney for some reason so I would burn coal for a few weeks then switch over to wood for a week or two. Ackually the wood would heat better, but with more trips to the furnace. Less labor in coal and longer burn time. Wouldn't trade my stoker now that I have one. for nothin.

That is very interesting!! What causes the coal ash to make the creosote come loose from the chimney? Some kind of chemical reaction?

I know a family who had a tall clay lined chimney and burned exclusively wood for many years.
They switched to a coal furace and were warned by their coal supplier that the coal exhaust WILL loosen all of the remaining creosote. After a period of time it did loosen all at once and ended up plugging the chimney at the bottom. Everyone woke up very sick and lucky to avoid a disaster.

THATS why you are supposed to CLEAN YOUR CHIMNEY at lease once or twice A YEAR with wood more like twice a year depending on what kind your burning SAFETY FIRST :shock:

I think that is the case, but it is not the fly ash, I believe it is the acidic nature of the gases.

I'd imagine the heat would have something to do about it too.

Being a professional chimney sweep I can tell you that it is basicly a chemical reaction thing. I have many customers that I encourge to burn coal along with their wood to help clean up problem flues. Burning coal is not a substitute to having your chimney inspected annually.........

i live in a home that has coal burning fireplaces , i was wondering does coal burning have a higher or lower risk of chimney fire , i have worked with wood burning fireplaces but never one of these little coal burners before, i am like any one else afraid of house fires , i live in an old home with very tall chimneys the house is 3 and 1/2 stories tall so i assume the chimney to be about 40 feet or so up . i actually have 2 chimneys which in total have 9 flues so my other question is if im only using one fireplace do i need all the flues cleaned or just the one to that fireplace , i wasnt sure if there is any heat transfer between them that could cause a problem if an unused one is dirty . thanks for any help
