SOLID FUEL MANUFACTURING METHOD AND MANUFACTURING DEVICE

摘要

A method and device manufacturing solid fuel, the method includes: mixing porous coal with a mixture oil containing solvent oil and heavy oil, to obtain material slurry; heating the material slurry to promote dehydration of porous coal and impregnating the mixture oil into pores of porous coal, to obtain dehydrated slurry; separating upgraded porous coal and the mixture oil from the dehydrated slurry; drying the upgraded porous coal by heating and conveying it while supplying carrier gas; setting a target value of the circulation amount of carrier gas and a target value of the pressure of carrier gas at the drying; calculating control outputs, based on deviations between the target values and measured values corresponding respectively thereto; and adjusting the supply amount of carrier gas, based on a smaller value between the control outputs obtained.
