[Stoves] Understanding "charcoal making" stoves. Was:energy lost in charcoal making and briquetting

[Kevin Chisholm]

Dear Jeff

If the consider the T-LUD or the IDD "devices" as a total package, we see 
the following:
1: A gasifier section
2: Purposeful features for the provision of secondary air with the intent of 
permitting complete combustion.

it is clear that the intention of the device as a total package is for it to 
be a combustion device, or a stove.

If the "combustion zone", was removable, then it would be a "gasifier with 
an optional  top burner." However, the top burner or combustion zone is not 
removable; it is purposefully built into the system, so that it can function 
as a device permitting complete combustion of pyrolysis gases.

Best wishes,

Kevin
