[Stoves] [Gasification] Heating/thermal usage - China workshop notes

[Ken Boak]

Paul,  Stovers and gasification enthusiasts,

Thankyou for your report on the proceedings of the ARECOP workshop.  Most
interesting reading.

It appears to me that applications 3,4,5 and 6 (below) could be met with a
T-LUD gasifier of between 20cm and 30 cm diameter.

Might this be a common designed element for these projects that could be
optimised and shared amongst the participants?

regards
