Abstract

Brassica napus L. (canola/oilseed rape) straw presents a suitable alternative combustion fuel due to its availability, relatively high calorific value and low moisture content. Pelletization enabled the bulk density of canola straw to be improved, enhancing its potential as an alternative combustion fuel. The aim of the research was to study the changes in the quality properties (i.e. abrasion resistance, compressive strength, particle density and pellet dimensions) of canola straw pellets during storage over a period of 48 weeks. The storage of canola straw pellets did not affect the abrasion resistance of the pellets. Whilst the particle density and compressive strength varied with length of pellet storage, no trend in these variations was observed. The length of the pellets decreased during storage due to breakage, whilst, the diameter did not vary during storage.
