Ecological and Energy Efficiency of Wood Pellets’ Production

Abstract

In the technological cycle of enterprises of the forestry complex, a significant amount of wood waste is generated, but due to their high humidity, low energy density and heterogeneous granulometric composition, they refer to difficulty combustible fuels. The perspective direction of their enrichment is granulation. The results of comprehensive study of the energy and environmental performance of industrial lines of granulation of byproducts of sow mill production are presented. The change in thermomechanical characteristics and the fractional composition of wood material in the process of granulation investigated. The components of the heat balance and emissions of gas release are determined. To determine the heat loss to the environment, an elaborated technology based on the application of a relative method supplemented with a television survey. Recommendations for improving the energy-ecological performance of granulation lines are presented.
