I have been looking for information on the use of coal in iron
foundries. While there is lots of discussion on the use of coal and
coke in blast furnaces, I can't locate much on foundries. It seems
clear that it would be possible to use coal in an air furnace, but
when does it happen? Is coal used, or must it be coke? How, if at all,
does the use of coal (as opposed to coke) effect the iron?
Any information or sources to look at is appreciated.
Thanks
Jim Brothers
