<p>The invention comprises: a pulverizer (23) for pulverizing low-grade coal (101) supplied from a raw coal banker (21); a fluidized-bed dryer (12) for drying pulverized low-grade coal (101A) which has been pulverized; and a dried coal supplying line (35) for supplying dried coal (101B), which has been dried by the fluidized-bed dryer (12), to a coal gasification furnace (14), whereby the dried and pulverized low-grade coal is supplied at a high efficiency to a gasification system which performs gasification. This makes it possible to achieve gasification by merely coarsely pulverizing and drying the low-grade coal, without using a coal powdering machine for powdering as in the prior art, whereby the device and utility cost can be reduced significantly.</p> |
