[Stoves] Is thermal efficiency an appropriate parameter?

[Philip Lloyd]

CO:CO2 ratio is a measure of the efficiency with which the fuel is burned.  The energy efficiency = energy delivered/energy fed, and for cooking the energy delivered is probably best defined as the energy required to raise the temperature of the pot and its contents plus the energy required to evaporate any water lost from the pot. The energy fed is basically the energy in the raw fuel supplied. Energy efficiency is probably a better term than thermal efficiency precisely because of the lack of clarity you have found.

Is thermal efficiency (as defined in water boiling test) an appropriate parameter to judge the performance of the stove or some kind of other efficiency parameter are better representative stove performance?

 

Kindly find two papers attached where the performance parameters are determined by ratio of CO/CO2. Is this a better parameter to judge a stove performance rather than the thermal efficiency.

Darpan
