CIRCULATING FLUIDIZED BED REACTOR FOR USING BUCKET ELEVATOR CAPABLE OF TRANSPORTING HIGH TEMPERATURE MATERIAL

摘要

The present invention relates to a circulating fluidized bed reactor using a high-temperature bucket elevator. More particularly, a bucket elevator is installed to mix high-temperature fluid sand discharged from a combustor with a solid fuel to be pretreated and then introduced into a pyrolysis gasifier. In the bucket elevator, pretreatment processes of various types such as drying, semi-carbonization, carbonization, partial pyrolysis, partial gasification and partial combustion can be realized through adjustment of temperature and residence time in the pretreatment.
