A method for a two-stage combustion of nitrogen-containing gas with low NOx emissions, in a combustion chamber having a precombustion section with inlet means for introduction of gas and air, and a succeeding secondary combustion section in open communication with the precombustion section, which comprises, introducing gas and air to a primary stage in the precombustion section to provide a fuel-rich mixture and effecting precombustion of the mixture at an air number of approximately =0.6 to 0.9, subsequently subjecting the reaction products from the primary stage to post-combustion in a secondary stage in the secondary combustion section at an air number of approximately l1.3 to 2, and feeding an inert substance via a multiplicity of openings in the walls of the precombustion section to cool the walls and separate the walls from the fuel-rich mixture undergoing decomposition and precombustion in the primary stage.
