AGING OF MECHANICALLY ACTIVATED WOOD: EFFECT ON THE BURNING ABILITY

ABSTRACT
One of the aspects for optimizing the powdered biofuel combustion technology is to ensure proper relationship between powder production and its delivery into the reactor. This paper focuses on the effect of a time delay between production and use of powdered fuel on its combustion efficiency using pine sawdust as an example. It was established that the ignition delay time increases with an increasing delay between powdered fuel production and use (i.e., the effect of sample aging takes place). A correlation between the ignition delay time, the amount of lignin radicals, and the sample’s ability to release volatile combustible matter is demonstrated.
