[Stoves] Comparison fuel consumption

[Crispin Pemberton-Pigott]

Dear Dieter

Does the Ben Stove have lower emissions per kg burned or per MJ delivered to the pot?

I want to consider how the emissions are reduced. While one can say, 'because it burns less wood the emissions are proportionally reduced' the reality is I expect that the reduction should be much more than that.

If it burns half the wood with half the emissions per kg then the emissions are 1/4. I speak here of course with reference to CO and PM.

I have seen, on the other hand, ‎seen stoves that saved fuel but doubled the emissions. I presume that is not the case with the Ben Stove.

Thanks
Crispin

Dear all,
Please find attached a picture for comparison of fuelwood consumption of traditional Three Stone Fire and Ben Stove. The picture illustrates the savings with ICS and cooking with retained heat. Of course besides the savings of fuel there are corresponding savings of emissions and burdens.
Kind regards,
Dieter
