摘要：
The invention relates to a process for cooling gases using a circulating fluidized bed technique, wherein gas is conveyed through a fluidized bed formed by circulating fluidized bed material so that part of the circulating fluidized bed material is driven along with the gas flow and whereby the circulating fluidized bed material entrained in the gas flow is separated from the gas flow and returned into the fluidized bed, and wherein at least part of the cooling is carried out by cooling the circulating fluidized bed material stream to be returned. The process is characterized in that substantially the entire cooling is realized by cooling the circulating fluidized bed material stream to be returned in a heat exchanger (10) separate from the gas flow duct, in which event the cooling of the gas stream is effected by means of the circulating fluidized bed material stream returned to the fluidized bed and having a temperature lower than that of the fluidized bed.
