Abstract

To solve problems concerning the unevenness in shape or size of a biomass fuel produced and concerning fluctuations in the degree of drying / carbonization of the biomass fuel caused by the kind of rawbiomass materials. A device comprising: a combustion furnace 12; a rotating drum 14 which includes a feed part 50 for raw biomass materials and a discharge part 52 for a biomass fuel 32 and in which drying / carbonization is conducted with the heat of the discharge gas generated in the combustion furnace 12; a tilting means 16 for tilting the rotating drum 14; a flue cover 18 for forming, between itself and the rotating drum 14, a flue for the discharge gas generated in the combustion furnace 12; a processing line 20 for making the shape and size of the biomass fuel uniform; and a return line 22through which some of the biomass fuel is returned to the combustion furnace 12. The feed part 50 is equipped with a screw conveyor 80 which feeds the raw biomass materials to the inside of the rotating drum 14 while rotating at the same speed as the rotating drum 14.

Description

technical field [0001] The present invention relates to a biomass fuel manufacturing device, in particular to the use of biomass raw materials such as weeds, trees, shrub stems, pruned branches and leaves, bamboo, young bamboo, ground cover bamboo, ground brocade, and waste wood. A biomass fuel production device that produces biomass fuel as a raw material. Background technique [0002] Currently, cheap and convenient fossil fuels such as petroleum and coal are used as fuels, and biomass fuels produced from wood and other plant-based biomass raw materials are losing their practical status in Japanese society. [0003] That is, 75% of Japan's land is covered by forests, and sustainable renewable timber resources are abundant but underutilized. In particular, weeds, trees, shrub stems or pruned branches and leaves, bamboo, shrub, ground cover bamboo, brocade, etc. are burned as waste or used in landfills, and these are actually The technology for utilizing waste as a raw mat...
