BA5206 Gasification and synthesis gas processing

Research output: Patent › Patent

Abstract

The invention relates to a method and an apparatus for heating a fluidizing agent for a fluidized bed reactor in which the fluidizing agent is fed to the fluidized bed reactor. The fluidizing agent is heated by heat of the process gas and/or heat of flue gas in at least one heat exchanger in which the heat of the process gas and/or the heat of the flue gas is utilized after the fluidized bed reactor, and the heated fluidizing agent is fed to the bottom of the fluidized bed reactor. Further, the invention relates to the use of the method.
