Title:
PREPARATION METHOD FOR ENVIRONMENTALLY-FRIENDLY SOLID FUEL USING WASTE FOOD MATERIAL AND ENVIRONMENTALLY-FRIENDLY SOLID FUEL PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2016/021787
Kind Code:
A1
Abstract:
The present invention relates to a preparation method for an environmentally-friendly solid fuel comprising a step of stirring a waste food material mixed together with chaff, oak sawdust, corn stalk, rice straw, barley stalk, wheat stalk, peanut shells, and coconut shells; a step of putting the stirred waste food material into a compressor and pressurizing the same at a pressure of 90 to 100 tons; putting the pressurized waste food material into a heating pot, and heating the same at a temperature of 400 to 600℃ for 20 hours; a step of removing water and gases from the heated waste food material to thereby form a primary molded charcoal; a step of adding silica, sodium chloride, starch, and water to the primary molded charcoal and stirring the same to thereby form a fuel mixture; a step of pressurizing the fuel mixture by using the compressor at a pressure of 90 to 100 tons to thereby form the fuel mixture into the form of solid fuel; and a step of drying the solid fuel at room temperature for a certain period of time and completing the manufacture of an environmentally-friendly solid fuel having a strength of 180 kgf to 250 kgf before combustion and an ash strength of 60kgf or more after combustion, wherein the waste food material is mixed with 90% of chaff, 2.4% of oak sawdust, 2% of corn stalk, 1.2% of rice straw, 1.2% of barley stalk, 1.1% of wheat stalk, 1.1% of peanut shells, and 1% of coconut shells, and the fuel mixture is formed by mixing 300g to 400g of silica, 200 to 300g of sodium chloride, 10g to 15g of starch, and 100g to 250g of distilled water into 1kg of the primary molded charcoal.
