Spouted bed circulating fluidized bed direct reduction system and method
摘要
A method and apparatus for producing direct reduced iron from iron oxide fines. The iron oxide raw material are passed through a pre-heater having a spouted port then to a primary spouted bed circulating fluidizing bed reactor and then to a bubbling fluidizing bed reactor. The reaction of the strong reducing gas mixture, through this series of beds allows intimate contact between the fines and small particles with the reducing gas to facilitate the direct reduction of the iron oxide fines to metallized iron.
