Mathematical model and process for the production of granulated fuel wood

Abstract

The results of a mathematical simulation of the process of wood flour granulation in the channels of flat dies are reported and a comparative analysis of currently available and developed mathematical models is performed in this work. A test bench based on a hand-power press and a bench for studying the compression of wood granules are described, and the results of full-scale experiments and the most significant results of the complex thermotechnical analysis of wood granules are presented. The effect of cooling conditions on the mechanical durability of granules is determined, and the dependences of the mechanical durability of the granules on the moisture content and temperature of a die are obtained.
