[Gasification] Gasification Digest, Vol 12, Issue 20

[awesales]

Hi Jeff
I would like to ask you if what you are referring to "char" is actual
charcoal or is it actually coal. I am building a wood gasifier with an eye
on a coal gasifier. I think the only way to do it is "fireballs" and have
seen some reference to this on these forums. I am not sure if their
reference to there charcoal is actually coal. Could you enlighten me?
Thanks
Ted
