LOW-GRADE COAL SUPPLYING FACILITY AND GASIFICATION COMPOSITE POWER GENERATION SYSTEM USING THE LOW-GRADE COAL

摘要

PROBLEM TO BE SOLVED: To provide a low-grade coal-supplying facility that can supply low-grade coal at high efficiency to a gasification system for gasifying the low-grade coal; and to provide a gasification composite power generation system using the low-grade coal and having the low-grade coal-supplying facility.;SOLUTION: The low-grade coal-supplying facility comprises: a pulverizer 23 for pulverizing the 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 the high efficiency to the gasification system which performs gasification.;COPYRIGHT: (C)2013,JPO&INPIT
