This paper includes both experimental and modeling studies of nitrogen oxides abatement. The tests were carried out in a quartz combustion chamber using laboratory equipment that allows measuring all thermal and chemical parameters of the process. An experimental test rig was constructed to determine the effect of the following "primary methods" on NOx concentration reduction: air staging, afterburning and flue gas recirculation. The effect of simultaneous use of the primary methods on NOx reduction was also studied. An obligatory element of experimental studies is numerical modeling of combination processes.
