[Stoves] Insulation and stove life

Sat Jun 8 16:20:35 CDT 2013

Dear Bob

Alexis' stove does not burn the gas in the insulated chamber. The temperature may well be below the upper limit for that material because it only deals with pyrolysing. 

Many attempts have been made to address this. The stoves from Envirofit are advertised as having a highly heat resistant metal (a form of oxidised aluminum) invented at Oak Ridge Nat Lab in the 80's. 

In general, metals have a low tolerance to flames unless they are cooled. 

The best way to use heat from cooling metal is to preheat air.
