Development of composition of pellet on the basis wood biomass from logging waste

Abstract

The real researches are directed on study of influence of waste of logging in compositions pellt on their main figures of merit. Woody biomass feedstock was to obtain experimental samples of pellets sawdust, pine needles and bark. Complex and contradictory nature of the influence of each component of woody biomass was studied on a set of properties of pellets. Found that the optimum content of the investigated components in the composition is sawdust – 70%, needles – 5% and bark – 25%. In this case the best combination of values of quality pellets obtained: density – 1.49 g / cm 3 , ash content 0.42%, and the mechanical strength – 6.5 MPa. Release on the results of studies conducted an experimental batch of pellets.
