Good catch there W.H. That little "oz." was too small for me to see!

At 16 oz. per pound that is about 3/4 pound of fines. I still wonder how much coal it took to get it.

When we were burning Superior coal, we were getting 3 measuring cups FULL for each tub of ash =around 150# of coal.With the Gale coal we are currently averaging less than a cup/tub full = around 170-180# of coal.

I would guess that 3 measuring cups full is more than my 3 pounds (half a coffee tub) of fines. And that is half of my 300 pounds coal. This means the coal itself is a big factor in how much fines end up in the pan.

When i stuck my hand into the load of Superior coal,while it was still on the truck,i knew by all the fines on my hand that we had a high fines ratio load of coal.

### Re: Quantity of fines

My coal barrel is a blue 55 gallon like most. After a full load, I'll see fines in the amount that would cover a tea cup saucer. I burned close to a TT load of rice (in one year) in the first year started. Switched to buck, I wanted cleaner material but it cut my consumtion by almost half. And less fines.

Dave, I expect the difference in consumption you observed was due to something other than the change in coal size. Either the coal itself was better, or something else you did made a big difference (didn't you change the boiler head?). I bought a TT load of buck one year and did not observe any difference in consumption in 3 EFM's burning it. To your point about it being cleaner, I agree - there was less fines.

A measuring cup is 8 oz, so 3 measuring cups is about half of your 3 pounds. I agree with your point that fines can vary a lot according to the coal source, but I don't think it's shown by these numbers.

. That is an old coal man's unscientific but very effective means of determining whether or not fines are excessive in coal.More reliable when the coal is fresh and damp.Just stick your open hand in and pull it out,the fines will stick.Keep getting that kind of feedback and you will gain confidence in the method.Did you come up with that yourself,or did someone give you the tip?Thanks for burning Gale Coal,by the way.

That was my first experience with rice coal,i just wanted to see what the load of coal "looked" like in my hand. I guess my "test" was an accidental education in coal quality.
