leijupetikaasutussysteemi and method of fuel kaasuttamiseksi leijupetikaasutussysteemissu00e4

摘要

The invention relates to a fluidized bed gasification system and a method of gasifying fuel in a fluidized bed gasification system, said gasification system comprising a fluidized bed gasification reactor and a fluidized bed combustion reactor, and in which a first fluidized bed reactor of said fluidized bed gasification reactor and fluidized bed combustion reactor is a circulating fluidized bed reactor, a first portion of there circulating means of which is arranged gas- tight inside the reaction chamber of a second fluidized bed reactor for gasifying fuel to be gasified by transferring heat from the particles of the fluidized bed combustion reactor through the outer wall of the first portion to the particles of the fluidized bed gasification reactor.
