OPERATION METHOD OF CIRCULATION DEVICE, AND LOOP SEAL

摘要

PROBLEM TO BE SOLVED: To reduce variation of particle circulation rate even with changing layer height difference in a circulation layer.;SOLUTION: There is provided an operation method of a circulation device in which particles move between a first flow layer and a second flow layer, for periodically supplying a gas supplied for promoting movement of the particles to a loop seal arranged between the first flow layer and the second flow layer. There is provided the loop seal arranged between the first flow layer and the second flow layer of the circulation device in which the particles move between the first flow layer and the second flow layer, and having a downcomer part, which is arranged in a side of the first flow layer and is a passage through which particles is introduced from the first flow layer, a riser part which is arranged in a side of the second flow layer and is a passage through which particles is discharged to the second flow layer, a particle pool part which is arranged in the side of the second flow layer and under the riser part, and a blow port for supplying a gas to the particle pool part.;SELECTED DRAWING: Figure 12;COPYRIGHT: (C)2019,JPO&INPIT
