Title:
DEVICE FOR PRODUCING BIOMASS FUEL
Document Type and Number:
WIPO Patent Application WO/2018/079470
Kind Code:
A1
Abstract:
[Problem] 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 raw biomass materials.
[Solution] 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 22 through 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.
