主 题：Pellets Miseanthus agricultural fuel combustion.
摘 要：It has been possible to pelletize wood Miscanthus mixtures （12.5%, 25% and 50%） without modifying production process settings of a softwood pellets plant. Pure Miscanthus material tested in the same conditions has led to unstable production, mainly explained by hammermill overfeeding. The unstable production has been identified as the main responsible factor of the low quality of pellets produced with pure Miscanthus for these trials. The produced pellets were tested in a 25 kW boiler and compared with agro-pellets of various origins： winter barley straw, rapeseed straw, reed, old hay, Miscanthus, and wood pellets. Results gained during these combustion trials allowed to describe combustion of these uncommon fuels and to characterize its emissions. The trials confirm general characteristics of agricultural fuel combustion： influence of the ash content on the gross calorific value, influence of the N content in the fuel on the NOx emissions, influence on the alkali content on the C12 emissions. But the influence of known parameter （S. alkali and earth alkali content） on SO2 emission might not be highlighted, while a relation with the fuel moisture content could be considered.
