This paper analyzes the methods of intensifying the combustion process of gaseous fuels in chamber furnaces. The characteristics of diffusion and kinetic combustion in burners, which are the main elements of the fuel system, as well as their aerodynamic modes and flame front stability, are examined. Changes in heat load are expressed in mathematical models based on factors related to the turbulent flame propagation velocity and the intensity of heat and mass transfer. In addition, ways to improve heat generation efficiency by increasing the flame surface-to-volume ratio, the advantages of slot and grid burners, the effect of preheating air and fuel, and environmental limitations are analyzed. The results make it possible to determine optimal parameters to increase furnace efficiency and ensure combustion stability.
