BIOMASS SOLID FUEL SUPPLYING APPARATUS

摘要

According to the present invention, a solid fuel supply device (100) comprises: a hopper (10) to accommodate a solid fuel; a stirring module (20) arranged to be rotated in the hopper (10); a gas distribution unit (30) arranged in the hopper (10); a transfer module (40) obliquely arranged from the lower end of the hopper (30) toward the upper part and has a screw feeder (41) to be rotatable thereinside; a gas flowing unit (50) structured to surround the transfer module (40); a solid fuel injection unit (60) which supplies the solid fuel discharged from the transfer module (40) to a reactor (1); and a control unit (70) which controls the rotational direction and speed of the screw feeder (41) by being connected to the stirring module (20). The transfer module (40) connected to the hopper (10) is obliquely arranged toward the upper direction such that the falling or the backward flowing of the solid fuel during the transfer of the solid fuel can be prevented. Therefore, biomass can stably be supplied in the required amount.
