Abstract

Disclosed herein is an apparatus for producing a refuse-derived solid fuel using combustible waste. The apparatus of the present invention includes a forming body (10) which has a hopper (10a) through which combustible waste is supplied into the forming body (10), with a drive unit (11) mounted to the forming body (10). The apparatus further includes a force-feed pipe (30) which is mounted to the forming body (10). Thermal oil flows through a space defined between layers constituting the force-feed pipe (30). A force-feed screw (50) is provided in the force-feed pipe (30). The apparatus further includes a siphon (70) which is provided in a space defined in the force-feed screw, so that thermal oil flows through the siphon (70), thus drying the combustible waste. The apparatus further includes a plurality of rod type heaters (90) which are disposed at the first end of the force-feed pipe (30), thus heating an outer surface of the compressed waste.
