FLUIDIZED BED DRYING FACILITY

WIPO Patent Application WO/2013/011542

A1

A fluidized bed drying facility is equipped with: a fluidized bed drying device (102) that dries lignite (101); a generated steam line (L1) that discharges water-saturated generated steam (104), which is generated when drying is performed by a heat transfer member (103), to the exterior of the fluidized bed drying device (102); an electrical dust collection device (105) that removes powder dust in the generated steam (104); a heat recovery system steam turbine (145) that is interposed downstream from the electrical dust collection device (105) and recovers heat from the generated steam (104); a branch line (L2) that supplies fluidizing steam (107); a cooler (110) that cools the material (drying lignite) being dried; a hot water spraying device (140) that is provided in the generated steam line between the electrical dust collection device (105) and the steam turbine (145), and that supplies hot water (142) at a temperature higher than or equal to the saturation temperature to the generated steam (104) from which dust has been collected; and a collection device (141) that collects and removes powder dust remaining in the sprayed water.
