[Stoves] Use of rebars in cookstoves

[Jock Gill]

Is there any thought on the minimum temperature required for a stove to be satisfactory?  It would seem that the cooler the combustion temperatures the longer the metal parts will last.  So what is the goldilocks temperature range: not too cold and not too hot?

My experience suggests that even simple tin can stoves will last a long time if the temperature range is around 700 degrees C.  I have made VERY high temp ND TLUDs which showed serious metal wear and tear after every run.  The outer sides of the cans would shed thin layers of metal dust that was much like rust.  At too cool temperatures, there is creosote buildup.  I control temperature by limiting primary air and balancing out the draft in the system.

I note that I like to run my iCan TLUDS above 600 degrees C in consideration of the quality of the charcoal/biochar I want to harvest as a co-product of the pyrolysis of biomass.

My practice now is to look for no visible creosote with no metal dust rubbing off at the end of a run.  IE not too cold and not too hot.  As in everything, it is about whole systems tuning for desired results.

Thoughts?

Regards,

Jock
