Title:
FLUID BED DEHYDRATION SYSTEM
Document Type and Number:
Japanese Patent JP2015014387
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid bed dehydration system capable of realizing the improvement of system efficiency by effectively utilizing the exhaust steam of a fluid bed drier.SOLUTION: In a fluid bed dehydration system 1A, having a vapor-flow fluid bed layer type fluid bed drier 10 for indirectly drying brown coal with the latent heat of super-heated steam, for obtaining the super-heated steam by introducing dry steam produced from the brown coal which is dried within the fluid bed drier 10 to a steam compressor 20 to compress the dry steam by the steam compressor 20, the fluid bed dehydration system 1A comprises a steam trace 30 for ventilating a dry-steam pipeline 21 for connecting between the fluid bed drier 10 and the steam compressor 20 with hot insulation steam, in which the exhaust steam of the super-heated steam discharged after the brown coal is dried in the fluid bed drier 10 is blended, after decompression, with drive steam supplied from a hot insulation steam supply source as the hot insulation steam.
