[TheForge] Forge firepot.

[wmullett at bright.net]

I know there are problems with acids leaching out of coal strip mines so I just googled acid & coal and found several sites that discuss this problem.  It appears the water reacts with the sulfer in the coal to form ... I guess sulphuric acid?

I know strip mine ponds typically don't support much life until their bottoms and the surrounding surface areas are covered with some humus.  I knew one guy that said some of the ponds were so acid you could feel it if you took a swim.

Walt,
I don't know for sure whether you'll get an acid from water+ coal or
ash.  Wood ash is alkaline (opposite of acidic).  Coal itself may be
somewhat acidic.  Burning stuff changes its acidity, sometimes a LOT.
But water plus anything ionic is corrosive.

I've never had a problem of clinkers sticking to the tuyere either but
then I also don't get many bad clinkers.  I know my coal is part of the
reason I have few clinkers but also I believe the fact that I use a hand
cranked blower is another reason.  

I also have as light gauge portable forge that has held up very well
for many years and it was original.  I've seen several old forges like
this that are still ok.  I think you can use gauge material with manual
blowers and if you are careful not to soak your forge in water when you
quit. 

Bruce - doesn't water react with the coal / ash and produce an acid?

I've never had a problem with clinker sticking to the firepot.  I've
used steel or cast iron firepots.  What are you using?

  Huge pieces of clinker can stick to the firepot and be hard to
remove<G>.
