Description

Technical Field

[0001] The utility model relates to the technical field of fly ash treatment of coal gasifiers, in particular to a storage bin device for collecting fly ash of a circulating fluidized bed coal gasifier. Background Art

[0002] During the fly ash collection process of the circulating fluidized bed coal gasifier production system, fly ash often deposits on the bottom cone surface of the fly ash storage bin due to its small density and small particle size; over time, more and more fly ash will deposit on the bottom cone surface of the storage bin, which is likely to block the ash outlet located at the bottom of the storage bin and affect the fly ash collection rate.
