Abstract
The invention relates to a process for reducing NO x emission in the thermal reaction (combustion) of nitrogen-containing fuels or in the reduction of waste gases or vapors containing nitrogen oxides by a multistage reaction in which, in a first stage, all the nitrogen oxides present or spontaneously formed are reduced in a substoichiometric fuel-to-oxygen ratio and, in a following second stage or in following further stages, are after-reacted until all the oxidizable reaction components have been completely reac-ted. To accelerate the reaction, the reactants are addi-tionally activated in at least one of the reaction stages by activation regenerators which statically mix the reac-tants with one another and contribute towards the equaliza-tion of heat flow. A furnace internally comprising a regenerator wall with throughflow openings is provided for carrying out the process.
