Method and apparatus for feeding oxidant into a combustion device

摘要

The invention relates to a method for feeding oxygen-containing gas (6, 9) into the combustion chamber (F) of a combustion device (V), wherein a subset of the flue gas stream (recycle gas) (5) emerging from the incinerator is subjected to a pressure increase and subsequently into the Firing chamber (F) is returned, and an apparatus for carrying out the method. An oxygen-containing gas, which is at a sufficiently high pressure (9), is added to the recycle gas (8) after the pressure has been increased.
