[TheForge] propane vs coal vs charcoal

[Jerry Frost]

I've done a bit and played a little making it.

The real trick setup though is a wood gassifier, it is 
way more efficient and produces plenty of heat to forge 
or melt. I don't know about using it on iron but lesser 
metals for sure and I don't see why it wouldn't melt 
iron.

This URL is a good one.

Agua Das has a rep as a serious inovator in the field 
of home made gassifiers, the "Dassifier." As usual, 
once you have an idea what to ask for web searches will 
provide more info than you want. <grin>

I'm planning a combo wood gassifier (NOT like one of 
these though) heat stove for the shop that'll double as 
a charcoal retort. It's based on the multiple burn zone 
wood stoves currently state of the art fo home heat but 
with a little twist.

A couple guys on Iforgeiron http://www.iforgeiron.com/ 
are building forges and melters based on gassifiers and 
have some pretty impressive results. They've been 
talking about it, posting pics, plans and URLs in the 
"Fuel" thread.

To answer your question directly. Yes. Look at the 
gassifier/melter in the first URL. The ejector type 
forced draft is in the center of the device between the 
gassifier and melter. This is another use of a jet 
ejector type induction device besides as a naturally 
aspirated forge burner with the rolls reversed. This 
one uses high psi air to induce the flamable gas 
instead of the other way around.

If it ain't forged
it ain't real.
Wrought iron is.
