[Stoves] Emissions from Residential Wood

[Tom Miles]

Crispin,

Emissions testing for residential appliances has concentrated on emissions
rather than energy efficiency so the ratings are for emissions at diefferetn
heating rates not for efficiency("smoke chart" in grams/hour at different
firing rates). 

The new ASTM standard for outdoor wood boilers may be more suited to cooking
stoves. That protocol tests for both efficiency (heat output in hot water)
and emissions. As far as I know the latter has not been officially
promulgated (published) by the US EPA. I'll find links to the test protocol.
I know at some boilers have been tested but I don't know if the results have
been made pubic yet. I do not know of similar tests in other countries.

What a great idea!

I like the part about giving a table for energy output based on the moisture
content of the fuel.

It is quite possible that a stove would be rated at two or three levels of
moisture and that the listing would give a benchmark (reasonably expected)
emissions level and specific fuel consumption.

If it were expressed in kg, not dried kg, it would mean something to the
average user instead of just stove geeks.

Tom, what do you think?  Will the national labs got for that in a standard?

Thanks
Crispin
