Process and apparatus for burning combustible constituents in process gas in a main combustion enclosure, preferably a thermal post-combustion device, whereby the main combustion enclosure is separated from a combustion chamber, into which oxygenic gas and gaseous fuel are fed, mixed and burnt. The fuel for the apparatus is fed through a lance which opens into a mixing chamber supplied with oxygenic gas, which is either itself the combustion chamber or merges with it, and the outer surface of the combustion chamber is exposed at least partially to the process gas. The fuel is burned completely or nearly completely in the burner combustion chamber and the mixture of burned fuel and gas leaving the combustion chamber oxidizes the combustible constitutes in the process gas flowing outside of the combustion chamber by yielding flameless heat energy to them.

Process for burning in a main combustion enclosure the combustible constituents of a process gas, said main combustion enclosure being separated from but in communication with a burner combustion chamber into which oxygenic gas and fuel are fed, mixed and burnt, said process comprising: feeding said oxygenic gas into an inlet section in communication with said burner combustion chamber, causing said oxygenic gas to swirl prior to mixing it with said fuel, mixing said fuel and said swirling oxygenic gas; directing said mixture into said burner combustion chamber, burning said mixture in said burner combustion chamber, and causing said burnt mixture to exit said burner combustion chamber and to oxidize the combustible constituents in the process gas flowing outside said burner combustion chamber by yielding flameless heat energy to said process gas flowing outside said burner combustion chamber.
