Title:
低品位炭を原料とする固形燃料の製造方法および製造装置
Document Type and Number:
Japanese Patent JP4045232
Kind Code:
B2
Abstract:
A method for manufacturing a solid fuel includes the steps of partially or completely separating finely powdered coal from pulverized low-rank coal; mixing the separated low-rank coal with a mixed oil containing a heavy oil and a solvent oil to produce an untreated slurry; heating the untreated slurry to dehydrate the low-rank coal and filling the pores of the low-rank coal with the mixed oil; and separating the solid fuel from the heated slurry by solid-liquid separation. The manufacturing method further includes the step of adding the finely powdered coal separated from the low-rank coal to the solid fuel produced by the solid-liquid separation of the heated slurry. The finely powdered coal separated from the low-rank coal has an average particle size of 0.5 mm or less. An apparatus for the manufacturing method is also disclosed.
