Influence of Lignosulphonate Addition on Poplar Pelletisation and Combustion

I. Mediavilla, N. Alfaro, L.S. Esteban & J.E. Carrasco
Poplar has demonstrated to be a tough material to be pelletised, and this makes the use of additives, like maize starch and lignosulphonate, to be considered in order to improve the process and the pellets quality. The objective of this work is to evaluate the influence of the addition of lignosulphonate on pelletisation process of poplar and their effects, regarding the SO2 emission and sulphur content in ashes, on combustion process. Poplar has been pelletised...
