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 JP4634900
Kind Code:
B2
Abstract:
A raw material slurry in which a coal is mixed with a mixed oil containing a heavy oil and a solvent oil is subjected to a water vaporization treatment with a vaporizer, and is subjected to solid-liquid separation with a mechanical solid-liquid separator. A separated solid is heated with a dryer while a carrier gas is flown, so as to vaporize the oil and produce a solid fuel. The carrier gas is fed to a cooler through a pipe, and the above-described vaporization oil is condensed and recovered. In a method and an apparatus for manufacturing a solid fuel, an occurrence of blocking in a pipe between the above-described dryer and the cooler can be prevented. An oil is flown on an inner wall surface of the pipe in the neighborhood of a cooler inlet portion with respect to the pipe between the dryer and the cooler.
