The Sweet Smell of a Campfire

Fuel moisture content has been mentioned in multiple biomass burning and cookstoves papers, but the effect it has on emissions from cookstoves is still unclear. This photograph was taken during the pilot testing phase of a study aimed at understanding the effects of fuel moisture content on emissions from stoves. Water droplets can be seen here coming out of the wet wood as it burns. Moisture in the fuel lowers the temperatures produced during burning, and reduced efficiency and smoldering create more pollution than dry wood does when it burns. This suggests that it might be advantageous for wood-burning homes to dry their fuel completely before burning to reduce the amounts of harmful pollutants for themselves and the environment.
