> The burner sketched at right enters through the outer insulation and outer

> The inner hard liner makes the furnace chamber and heating volume. It is

> 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.

> number of things, a recuperative wall furnace being one.
