Small Scale Pilot Combustion Experiments with Wood Pellets – The Effect of Pellet Length
University of Eastern Finland,
School of Forest Sciences, P.O. Box 111 FIN-80101 Joensuu, Finland.
ABSTRACT
The primary objective of this study was to observe the effect of pellet length on utility and combustion temperature. Pellets with various lengths were combusted in a pellet stove. Pellet length was found to have a significant effect on the combustion temperature and stability. Increasing the length of pellets from 5.8mm to 13.1mm decreased the average burning temperature by 31% and flue gas temperature by 25%. The major determinants of combustion efficiency derived from pellet length were assessed.
