[Stoves] Lime residue in stack?

[Anand Karve]

Dear Frank,
If the fuel is mineral coal, it can have a lot of calcium in it. In India,
the fly ash from electricity generating plants used to be given free of
cost to farmers for spreading it on the fields, But nowadays it is used for
making bricks and pavement tiles. If the coal has calcium in it, I am quite
sure that a part of it would stick to the smoke stack. I do not know
the chemical form it may be having. It could be calcium silicate.
Yours
A.D.Karve
