[Stoves] Pot size influences performance

[Crispin Pemberton-Pigott]

Dear Friends

 

I just clipped this chart, Figure 10, from 20100202 DUE Heterogeneous
testing Robinson Makonese Pemberton-Pigott and Annegarn.pdf which is in the
list of documents at
http://www.newdawnengineering.com/website/library/SeTAR%20Centre/

 

It shows something unusual about a stove cooking with two different pots
(not at the same time). The thermal efficiency is almost always better for a
large pot than a smaller one, but this is not always the case. Assume
nothing.

 



 

The thermal efficiency of the small pot was higher on low power than the
large one, and the reverse was true at higher power. Low power flames can be
very unstable to don't read too much into this, other than make no
assumptions - test the combination (stove+fuel+pot) to find out what the
performance actually is.

 

Regards

Crispin
