Clinker Pics

Here's a huge Blashak clinker I just pulled out of the Crawford 40.

When you get bigguns, post pics!

Are these typical of what you get in an older stove? My Blaschask clinkers are 25% of that size if that.

This one is from Tractor Supply Kimmel's nut that I posted about recently. Jammed the grates open. Lots of fused iron and hard as stone.

Well, it is stove size coal but I don't think the stoves age has much to do with it. I could be wrong.

I had one once, that was shaped like Abe Lincoln. it's in the Smithsonian if you're interested.
So what are you saying, Scott? "Bigger is better"?

Lol!

It almost did not fit through the drop grate

....almost looks like some peanut brittle from the cookin' with coal thread.

Just curious......how hot are you running the Crawford to get a clinker like that?. I've had the #8 up to 600 on the barrel and I have yet to see a clinker.

The Crawford fire pot can run a lot hotter because it has less heat loss.

Less heat loss up the chimney or into the room?.

That's something we haven't tried cooking,......... yet ! At least give me a chance to screw it up before ya put the digs in, will ya ?

Heat loss up the chimney.

Your grates grind up ash, mine just dump through the center sliding grate and around the periphery it gets somewhat ground up.

Here is a picture of a setup similar to the Crawford 40......

You say the Crawford "can" take up to 600* because it's more efficient. Can the cast grates last at those temps, or will they distort in time from those temps? My stove hit 600* when I fired it up on wood, and I was afraid the glass was gunna pop, the heat exchanger would split at the seams, and the grates would start melting into the ash pan. Don't know if my worries were justified.

I'd bet the smell would be cause for nonstop eating/drooling.

So what temps are you running at to form these clinkers?.

Well I'm sure if you let ash get close to the grates you can overheat them just like any other stove. The interesting thing is that the ashpan is so deep, that you'd have to really neglect the stove to do that.

On the coldest days last year with the Crawford No 2, I'd run 650 regularly to keep the house warm.

Last week with a couple days below 20 I've run the 40 up to 550* and the house was 76*
