Zusammenfassung:	The present disclosure provides a method for distributing gas for oxy-fuel combustion on a circulating fluidized bed. In the method, the gas is provided by three stages into a furnace of the circulating fluidized bed. The method includes: blowing in a first-stage gas containing oxygen and recycled flue gas from the bottom of the furnace; blowing in a second-stage gas containing recycled flue gas from a transition zone between a dense-phase zone and a dilute-phase zone of the furnace; and blowing in a third-stage gas containing oxygen from a side wall of the furnace.
