Impact of the Physico-Chemical Characteristics of Agro-Fuels on Combustion Emissions

C. Mignon, P.-H. Dricot, F. Van Stappen & M. Temmerman
Agro-pellets of various origins were tested in a 25 kW boiler: winter barley straw, oilseed rape straw, reed, old hay, miscanthus, wood-miscanthus mixes in different proportions (12.5% -25% and 50%) and wood. O2, CO, CO2, CH4, SO2 and NO emissions were measured during the tests. The flue gas chlorine (Cl) content was also determined and the data were linked to the specifications of the fuels used. Overall, agro-pellets burn less well than wood-miscanthus mixes and...
