The present invention relates to a method for manufacturing eco-friendly solid fuel, the method including: stirring a waste food material mixed together with chaff, oak sawdust, corn stalk, rice straw, barley, wheat stalk, peanut shells and coconut shells; putting the stirred waste food material in a compressor and pressuring the stirred waste food material with a pressure of 90 to 100 tons; putting the pressured waste food material in a heating pot to heat the waste food material at 400 to 600°C for 20 hours; removing moisture and gas from the heated waste food material to form a primary molded charcoal; putting silica, sodium chloride, starch and water into the primary molded charcoal and stirring the mixture to form a fuel mixture; pressuring the fuel mixture by using a compressor with a pressure of 90 to 100 tons to form the fuel mixture into the shape of solid fuel; and drying the solid fuel at room temperature for a certain period of time and completing the manufacturing of the eco-friendly solid fuel having a strength of 180 kgf to 250 kgf before combustion, wherein the strength of ash after combustion of the solid fuel is greater than 60 kgf. The waste food material is characterized by being mixed with 90% of chaff, 2.4% of oak sawdust, 2% of corn stalk, 1.2% of a rice straw, 1.2% of barley, 1.1% of wheat stalk, 1.1% of peanut shells and 1% of coconut shells, and the fuel mixture is formed by mixing 300 to 400 g of silica, 200 to 300 g of sodium chloride, 10 to 15 g of starch and 100 to 250 g of distilled water to the primary molded charcoal. |
