Coal dust bricks again
Coal dust bricks again
I've been reading through the old posts on this subject and wonder how wallpaper paste would work. Just flour and water.
Three of us sifted Penn Coal yesterday and got about 4 equal buckets per bag of: dust, 1/4" bits, 1" bits and over 1" size. Sure was a lot of dust; more than 25%.

What do consumers of train carloads of coal do with the dust?
I'm sure it's more than a few buckets and probably has enough BTU's in it to be worth doing something with.

Modern boiler use pulverized coal sprayed in.
Re: Coal dust bricks again
I would use corn starch and water mixed with the coal dust. Put the mix into styrofoam egg cartons and let dry. This so the dried lumps can be easily broken apart.

I just burn the dust as is. Mix it with the coal. Never had a problem.

Re: Coal dust bricks again
Exactly. All of the 'chunks' are pulverized before they are injected into the firebox. So whatever 'arrives' in a dust-like state just gets burned along with all the rest.

Re: Coal dust bricks again
Fred, you’ll have to experiment. I would start with one part starch and 10-15 parts coal (enough water to make it stick together) and adjust from there. I know Don Saager puts his mix into paper cups, but it seems to me that egg cartons would be reusable and cheaper.

Re: Coal dust bricks again
Thanks, I like the egg carton idea. May have to start with cups till I collect egg cartons. It will take a lot of either.
I have been throwing it into the firebox but I still have end up with a 5 gallon bucket of dust from 2 bags of coal. My friends have been sifting it for a couple of years and have about 150# of the dust/1/8" coal. Shame to throw it away.

QUESTION: Considering the cost of coal and the finite limit on life, which is more important, pasting pieces of coal dust together or making something new and worthwhile in your shop? Only asking.
