NOVELTY - A fuel recycling apparatus has a steam separator which is filled with filler of polymer material to eliminate liquefied moisture contained in biogas produced from an anaerobic digester tank, hydrogen sulfate-ammonia eliminator which is connected to steam separator through a pipe and formed with secondary iron oxide and activated carbon layer to absorb and eliminate hydrogen sulfate and ammonia, particulate substance removal filter which is connected to hydrogen sulfate-ammonia eliminator through pipe, and eliminates particulate substance, and biogas compressor(40).    USE - Fuel recycling apparatus of biogas is used for micro turbine.    ADVANTAGE - The biogas fuel recycling apparatus has excellent workability and moisture resistance, and is economical.    DETAILED DESCRIPTION - A fuel recycling apparatus has a steam separator which is filled with filler of polymer material to eliminate liquefied moisture contained in biogas produced from an anaerobic digester tank, hydrogen sulfate-ammonia eliminator which is connected to the steam separator through a pipe and formed with the secondary iron oxide and activated carbon layer to absorb and eliminate hydrogen sulfate and ammonia, particulate substance removal filter which is connected to the hydrogen sulfate-ammonia eliminator through pipe and eliminates particulate substance, biogas compressor which is connected to the particulate substance removal filter, and pressurizes the biogas passing the particulate substance removal filter, a biogas cooling moisture eliminator (50) which is connected to the biogas compressor though outflow pipe to flow in the biogas passed to biogas compressor through the outflow pipe connected to the compressor, and eliminates gas-phased moisture by cooling biogas through heat exchange media, and removes the cooled biogas to biogas compressor to promote heat exchange, and siloxane-moisture eliminator (60) in which the gas-phased moisture is eliminated by the biogas cooling moisture eliminator and which is connected to the biogas compressor through pipe to flow in the biogas heated by the heat exchange in the biogas compressor and formed with silica gel layer and activated carbon layer to eliminate the moisture and siloxane.
