MANUFACTURING METHOD OF WOOD PELLET FOR BIOMASS GENERATION USING MEAGRE WASTE WOOD

摘要

The present invention relates to a method for manufacturing wood pellets for biomass generation using meagre waste wood. More specifically, the present invention manufactures the wood pellets for biomass generation using the meagre waste wood such as forest tree waste, damaged tree, industrially processed waste wood, construction waste wood, life waste wood, logistics waste wood, etc. in which there is almost no lignin ingredient, whereas adding a carbon source like coke powder to enhance a calorific value and bio energy density as a fuel for power generation and, at the same time, adding a binder like pitch to perform a forming process at temperature and pressure much lower than conventional wood pellet forming conditions. Thereby, the present invention drastically saves energy consumption during a processing operation, so mass-producing the wood pellets proper for the biomass generation with lower costs using the meagre waste wood of which raw materials are easy to obtain and are cheap to purchase. Therefore, even the ash, remaining after burning the wood pellets, can be used as a soil activation agent and a fuel as well as commercialization of the biomass generation can be promoted.
