【発明の名称】循環流動床系内の固形物分布を改善する方法
Document Type and Number:
Japanese Patent JP2657526
Kind Code:
B2
Abstract:
Disclosed is a process for improving the solids distribution in a circulating fluidized bed system. In the invention, hot ash from the system and fresh carbonaceous fuel are mixed in a chamber which is fluidized so as to form a fluidization zone wherein the heavier material is concentrated and a second fluidization zone which consists predominantly of fines at least a portion of which is separated from the heavier material. This zone separation is facilitated in part by maintaining different gas-mass flow rates so as to form a plug of heavier material. At least a portion of the fine material is then transferred into the reactor while the coarse material is further processed.
