<P>PROBLEM TO BE SOLVED: To provide a gasification furnace that includes a char-collecting facility configured simply and inexpensively. <P>SOLUTION: The coal gasification furnace 10 generates a coal gas by heating powdered coals produced by pulverizing coal in a pulverizing unit 20 to pyrolyzing the powdered coals, wherein the coal gasification furnace includes the char-collecting facility 30 that collects the char in the generated gas for reuse. The char-collecting facility 30 includes: a char separation and collection unit, such as a cyclone 31, for separating the char from the coal gas to collect the char; a heat exchanger 35 for cooling the char in conveyance; a char bunker 28 for storing the char after depressurization and supplying a predetermined amount of the char to the pulverizing unit 20; and a char conveying line 34 for conveying the char from the char separation and collecting unit to the pulverizing unit 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
