2 old American Standard boilers.
Guessing from the old serial numbers to be 1951.
I could not believe how much soot came out when I tapped the flue on one.
First clue was when I saw the clay liner at top of the chimney.

Were those pieces of soot hard?
On a smaller residential oil boiler, I have seen small hard pellets of a glassy creosote-like substance. This happens when an internal water leak interferes with/subdues the fire and the fuel does not combust completely leading to the hot unburnt hydrocarbons forming the creosote like product.
Nah…
More like powder and got all over my nice Inspection pants.
Looked like mini klinkers , if you are old enough to remember coal and steam Kewanee
This one is from the day before.
My old man used to pay me $5 an hour to shovel the coal into the worm feed and pull out the klinkers.
Man Bob You must be older than dirt !!!:):p:D
You mean soot:)
They all converted to gas around 1972-73
Price of coal at that time was a sky high $17 from what I recall.@ton
$5 an hour was good money in 1915! :p:mrgreen:
Now I know why everyone migrated north. The BIG Bucks I was paid .50 and that is cents an hour to shovel chicken crap do you realize how much crap one can shovel in one hour:shock:
