[Stoves] Report on Improved Dung Burning Stove in Tibet

[Kevin Chisholm]

Dear Mike

While the stove system shown on the Bioenergy Lists Site appears to be 
vented outside the Living space with a chimney, have you, or others, done 
any work to measure the dioxin content of flue gas from dung burning?

If not, would you, or anyone else know of any measurements of dioxins in the 
products of combustion from dung burning?

In addition to the readily recognized concerns for Indoor Air Quality when 
biomass is burned in a home without positive means of removing the 
pollutants, dung burning may have a serious additional hazard, in the form 
of dioxins. Are you (or anyone else) aware of any work indicating that dung 
fuel does, or does not, create a dioxin hazard when products of combustion 
from dung are vented inside the living space?

Thanks.

Kevin
