[Stoves] Lime residue in stack?

Dear Anand,

I have yet to receive the sample but am hoping it will work for this
interesting project. If it is made of carbonates or oxides it will work (I
think) but silicates or lots of organic material will just be a problem as I
see it now. 

 

Thanks

 

Frank

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

Greetings Stovers

 

I am being asked to test a sample of a "lime residue" from a stack of a
power plant(?) to see if can be used in agriculture or in chemical
manufacturing. Is there such a thing as carbonates or oxides formed in
stacks? In pure enough quantity. I was thinking most all the residue was
from organics (tars) depositing on the walls. Not sure what the fuel is but
I think is a big operation in Australia.

 

Thanks

 

Frank
