Pellet / Clinker question

[Donn Fletcher]

Okay I have a question. I started buning Turman pellets in my Harman XXV. The only other Pellets I've used has been NEWP. Those created a ton of soft fluffy like ash at the edge of the burn pot. Now burning the Turmans I'm getting hard black chunks that don't seem to easily be pushed in to the the ash pan it seems like fresh pellets fall on top of the hard chunks and build up like a wall. My question is does that sound normal for those pellets are those chunks Clingers. What I have been doing is when I see it happening I use the scraping tool to break up the bottom wall.

What is your feed rate set at?

 

[Donn Fletcher]

I have a different stove but find different brands produce different amounts and texture of ash. With Lignetics I get soft fluffy ash, with Somersets I get the black chunky ash you describe for Turman pellets. Overnight with Somersets I get less volume of ash, something like a birds nest about the consistency of burnt toast. I believe the Somersets put out more heat but find both acceptable.

Oak pellets have a heavier ash than most other hardwoods. As long as it isn't big chunks of rock hard and in some cases shiny? I'd just give it a quick swipe once a day.

You could try lowering the feed rate a little, But you might loose some heat. There are a couple of Harman owners that are burning Turmans on the board. Hopefully they chime in for you. newf lover is one member I know of, You could send her a PM.

I've had the exact same experience burning Turmans in my XXV. When burning Oakies, I have almost no burn pot build up, but with Turmans, I get both the hard ash you describe and significantly more hard scaling on the burn pot.

I scrape the burn-pot weekly, FWIW.

How were the Okies I may try them for Febuary

 

[thedude110]

They burn clean and throw good heat -- what more can I ask?

Want to try these Oakies I keep hearing about. Anyone from Vermont know where I can get some?

I am burning dry creek now, and they make the same chunky clinkers. I need to clean pot every day and a half. My castile loves oakies but could not get them this year.
