Method of the development - mathematical models and computer codes preparation for computation of the thermal and ecological indexes of the burners. Testing procedure - physical and mathematical description of the transport processes for momentum, mass and heat in the reacting flow with simultaneous development of the global mechanisms of the natural gas (methane) combustion and NO formation. The obtained results adaptation with the experimental data of the formation temperature and concentration of the nitrogen oxides yields. The obtained results and novelty, efficiency of development and field of using - For the first time the Reduced kinetic mechanism of natural gas combustion with a set of kinetic constants concerning two-stage combustion and reaction products recirculation is created. The original mathematical model for computation of dynamics of NO formation during of the burning reactions is developed. The co mplex mathematical model and computer code for computation of the combustion systems is developed. The computation results and experimental data obtained at the fire tests of the radiative tubes of IGT's construction in the wide range of furnace temperatures, variation of the separate construction elements and burners operation characteristics are compared. The reliability of the computational model for conditions of the optimization of two-stage gas combustion in high temperature devices with burning products recirculation is confirmed.
