PROCESS AND DEVICE FOR FEEDING OXIDIZING AGENT INTO A COMBUSTION SYSTEM

摘要

A process and device for feeding oxygen-containing gas into the firebox of a combustion system is disclosed. A sub-quantity of the flue gas stream exiting from the combustion system (recycle gas) is subjected to pressure elevation and subsequently recycled to the firebox. An oxygen-- containing gas which is present at a sufficiently high pressure is added to the recycle gas downstream of the pressure elevation.
