Correct S.S. Liner to burn Anthracite Coal

PostBy: mills4135 On: Mon Feb 03, 2014 11:10 am

Hello; I have been burning Wood but want to switch to Coal,i have a brick chimney with a 7" 316Ti liner,will the liner stand the corrosiveness from the sulphuric acid from coal burning.Manufacturer was no help,kind of hedging his bets i kind of lost faith when he was confusing soft coal with Anthracite,and insisting soft coal would be just fine,i've always called Bituminous coal soft and with more acid producing smoke than Anthracite coal. So can anyone tell me if the 316Ti liner will handle the corrosiveness. Thanks Don.

Don, 316ti is the proper alloy to burn anthracite. Does your brick chimney have a terracotta liner? If so you really wouldn't need the ss liner.

316Ti is as good as your gonna get for SS ..... but that doesn't mean it still won't rust out eventually. Masonry is the only way to go.

Like Kirk said - if you have a terra cotta liner, scrap that SS liner. There's just no point in using it.

Thanks gentlemen,unfortunately the only liner in the brick chimney is the S.S, 316Ti. Does anyone have an educated guess on what to expect for ballpark life expectancy of the liner burning 4 or 5 ton of Redding Anthracite a year? Regards mills4135

I chose AL29-4c because of its superior corrosion resistance over 316 stainless at typical anthracite coal flue temps.

Some say it is not structurally as good at higher flue temps, ie +600F, but since my flue temps never approach that, I figure I'm good.

Yeah it's a crapshoot - all depends on how much flyash sits in there during the off season, and, how much moisture gets inside - that's the big one. Lots of moisture will destroy that pipe easily in just one summer's time. If kept clean and dry, you could get 10 years out of it. Or, anything in between ....


To quote Sting .... "It depends" . ;)

Excellent point Smitty.

Yup, I schedule my sweep when I have 30 bags of coal remaining so it's swept as soon as the chimney is cold on or around April 1.

Unless you chimney has holes or large cracks you don't need a liner, stainless or otherwise. If it drafts well, you are fine.

I agree - been running coal for going on 9 years now in an unlined, crumbling masonry chimney, with two 45° jogs in it in 2 different directions. No smell on the second floor ever, either. If I yanked on any one of those bricks with my bare hands, they would slide right out. :lol:

Hey Smitty, I'm running the same type of old chimney (45 ft interior to the house) , no liner and it works great. I just clean out the bottom, and the thimbles in the spring and the stove of course. Sometimes have too much draft, -.05.-.06 when really cold and burning really hot.

The AL29-4c stainless steel alloy idea interested me so I emailed Selkirk about it. They said it will not meet code for use with coal and they do not recommend it.

yes, it will meet code. However, it's not what's best. "Code" currently doesn't understand what's best and neither do the liner mfgr's. The best thing you could have is a tile lined masonry stack, the second best with coal is an unlined stack that drafts properly and is in sound shape. Stainless liners don't make things safer with coal and may increase danger because of potential rot, collapse, and subsequent flue blockage.

The funny thing about codes is that I find they are enforced by the whim of the inspector signing off on the job.

Where I live I had to have a "liner".... The 9x13 tile liner was not good enough according to the fire chief and building inspector!

The fire chief thought that the flue would be too large and not supply sufficient draft under the right conditions.

You only "need" to have common sense and what the building inspector requires :mrgreen:

Doesn't matter 'cause after spending time reading this forum I knew I had to become a coalie at any cost!

I'll keep everyone posted on the condition of my AL29 liner after every cleaning/inspection so all can benefit
