[Stoves] Re tar in P-gas

[Crispin Pemberton-Pigott]

Dear Paal

 

Thank you for emphasizing that the fuel makes a difference to these
formations. A study of stove fuel moisture and its effect on emissions (not
a different fuel, just a different moisture level) was undertaken by
Ernestine Yuntenwi
http://opus.kobv.de/btu/volltexte/2008/458/pdf/diss_ernestine_pdf.pdf which
showed considerable variation in emissions even if the stove and pot were
the same. Different stoves react in completely different ways to a similar
change in fuel moisture. Some might stop operating altogether.

 

Regards

Crispin

Dear Stovers

There are at least three troubles on the cooking pot caused by stove and
type of fuel while cooking.

1.	Soot, which is easy to clean
2.	Tar, which is more troublesome to clean
3.	Pitch, which is more like varnish and really difficult to remove. 

Which one of 2 and 3 are we talking about? All of them are possible to avoid
by using TLUD-ND with a good balance between the primary and secondary air,
and distance to the pot, but it differ a bit with type of fuel.

Regards Paal W
