[TheForge] Recuperative Wall furnace sketch.

[Jerry Frost]

I uploaded a sketch of the basic recuperative wall furnace. Unfortunately 
Photoaccess has changed the way it does things and before I realized it I'd 
uploaded the sketch, meaning I didn't get to put it where I wanted to so 
it's under a march 2006 album rather than forges, etc.

Okay, that said the sketch is pretty self explanatory but here's a brief 
description of how it works.

The burner sketched at right enters through the outer insulation and outer 
hard liner with minimal gaps. The burner nozzle stops at the inner hard 
liner aiming across the gap to a larger port in the inner hard liner.

The inner hard liner makes the furnace chamber and heating volume. It is 
supported on standoffs. The exhaust port(s) are shown in the chamber floor 
below the burner port but may be almost anywhere. They do need to be placed 
so as not to allow exhaust gasses to leave the chamber sooner than possible. 
The labeled support is also noted as a baffle, this is to force the exhaust 
gasses to pass all the way around the chamber before being drawn back into 
the burner port. There should be a couple gaps in the baffle to allow 
complete exhaust circulation.

This is the basic idea. It's complexity is one reason I haven't built one. 
Still, once I have my shop up and online I plan on experimenting with a 
number of things, a recuperative wall furnace being one.

it ain't real.
