I'm highly tentatively guessing it's somewhere around 2.6 lbs./gal., but if you have actually weighed it as well as volume measured it in the past, I'd like to know some actual weight per unit volume figures for anthracite coal ash.
I'm also highly tentatively guessing that by volume it is about 1/3 of the original coal, volume for volume. Wherein roughly every 33-1/3 gallons of coal generate ~10 gallons of ash.

Ash from a stoker, and from a hand fed are going to be totally different as the hand fed grinds up the coal ash making it like a powder.
So are we just talking stokers?
Or more specifically just AHS?

Here’s my very rough calculations...
52 gallons of coal per week, about 12-13 gallons of ash.

I do notice a substantial amount of settling when I move the ash can out to dump it. From the basement, up a set of stairs, then it takes a sled ride that's a little bumpy about a 100 feet to where I dump it.

Best to weigh it straight from the furnace, but as was stated above, the grates have likely already compacted it a bunch.

Ash weight by volume really cannot be just estimated, sometimes ash will be "fluffy" and take up more volume and other times it will be "powdery: and take up less volume. To get a true value each sample should be weighed....

There are indeed a number of variables to "weigh" and take into consideration, but they are not world beaters that would cause one to abandon a quest. They merely add to the magnitude of the +/- error bars in the interpretation of the data.freetown fred wrote: ↑Wed.
