[Stoves] Definition of char-making appliance

Mon May 6 10:06:59 CDT 2013

Dear Char Producers

What is your opinion of this definition of a 'char making appliance'?

Char Making Appliance

Any appliance that derives heat largely from the pyrolysis of biomass in a
manner designed to produce, as a result of such combustion, a carbonaceous
byproduct high in carbon, useful as a fuel or as a 'biochar' and where such
product contains not less than 15% of the carbon in the original fuel.

If you have a suggestion for an alternative % of carbon, or wish to propose
a mass-based metric, please provide a supporting case.

Thanks
Crispin
