Study of Emissions from Domestic Solid-Fuel Stove Combustion in Ireland by Arigna Fuels

A study has been published by Arigna Fuels that explored the emissions from domestic solid fuel stove combustion in Ireland. 

Emissions from five solid fuels were quantified using a “conventional” and an Ecodesign stove. PM measurements were obtained using both “hot filter” sampling of the raw flue gas, and sampling of cooled, diluted flue gas using an Aerosol Chemical Speciation Monitor and AE33 aethalometer.

Overall, the PM EFs ranged from 0.2 to 108.2 g GJ–1 for solid fuels. The PM EF determined for a solid fuel depends strongly on the measurement method employed and on user behavior, and less strongly on secondary air supply and stove type. Kerosene-based firelighters were found to make a disproportionately high contribution to PM emissions. Organic aerosol dominated PM composition for all fuels, constituting 50–65% of PM from bituminous and low-smoke ovoids, and 85–95% from torrefied olive stone (TOS) briquettes, sod peat, and wood logs.

Torrefied biomass and low-smoke ovoids were found to yield the lowest PM emissions. Substituting these fuels for smoky coal, peat, and wood could reduce PM2.5 emissions by approximately 63%.
