[Stoves] Don't waste the heat, grow red wigglers and glorious greens

[Alex English]

Andrew,

The "second stage" chamber is a large water tube heat exchanger which, 
by design, the flame from the gasifier enters.
It is large enough to accept large wood in the event of an automation 
failure of the  chip system. In this mode or in combining modes, any 
"sophistication"  will be lost. Changes in air metering, air mixing  and 
residence time will compromise combustion quality even before the "air 
is shut off". Offgas is likely condensing on/in tubes, chimney and our 
atmospheric commons.

Why worry?
