Coal reforming method and coal reforming apparatus

A coal reforming apparatus comprising:

• a fluidized bed drying and classifying device which classifies a coal into a coarse coal and a fine coal while drying the coal;
• a carbonizing device which performs carbonizing on the dried coarse coal, so as to reform said dried coarse coal into a carbonizing gas and a char;
• and
• a combustor which is supplied with at least a portion of the carbonizing gas or an external fuel, and at least a portion of the fine coal and which supplies a heat, obtained by burning the carbonizing gas or the external fuel and the portion of the fine coal, to at least one of the fluidized bed drying and classifying device and the carbonizing device as a heat source.

A coal reforming method comprising:

• drying a coal by a dryer;
• performing carbonizing on the dried coal by a carbonizing device, so as to reform the dried coal into a carbonizing gas and a char;
• classifying the char while cooling the char by a fluidized bed cooling and classifying device to separate a fine char from the char;
• obtaining a heat by supplying at least a portion of the carbonizing gas or an external fuel, and at least a portion of the fine char, to a combustor and burning the portions;
• and
• supplying the heat obtained by burning the portions to at least one of the dryer and the carbonizing device as a heat source.
