[Stoves] Stove testing with and beyond the WBT

[Crispin Pemberton-Pigott]

Dear Ron

 

It was great to see you at the conference – been a long time.

 

Three brief points: 

 

1.       Testing TLUD’s and pellet stoves can be used by using the Burn Out Protocol developed for BP. It is reported in detail by Penn Taylor in a paper by him and in an ETHOS presentation (2009) which is available online. Not too sure about accessing the paper. I believe it can be refined further to consider more accurately the stoves that burn the charcoal at the end (Oorja etc) but it is a simple and pretty accurate test of some things like the total energy required to do something.

2.       You mention the time required to operate the stove. This is a major consider for the cooks/owners. It rates high on their list of stove attributes in some places. People are busy. It will be on Cecil’s list of social impact assessment questions.

3.       Char production as a % of dry fuel mass is easy: remove all ash from the char-ash mix. At present the char is weighed together with the ash with both being counted as unburned charcoal. This was discussed here recently.

 

Regards

Crispin
