The question of oil gas utilization today is very important.In the development of domestic micro-gas-turbine utilization power plants, the central place is occupied by the creation of a universal combustion chamber, which would ensure stable combustion of ballasted gases at different fields under variable operating conditions.In this work, the phlegmatization method was used to determine the lower and upper concentration limits, which allows taking into account the effect of ballasting components on the combustion limits. When calculating the coefficients of excess air at the upper and lower limits, the influence of the composition, temperature, and supply pressure of the components was taken into account.An analysis of the results showed that taking into account the parameters of air and oil gas at the outlet of the compressors expands the limits of combustion by the coefficient of excess air. An additional regenerative heating of the air between the compressor and the combustion chamber shifts the combustion stability region in terms of the excess air coefficient towards rich mixtures. Recuperative heating of fuel gas shifts the area of sustainable combustion towards lean mixtures. Simultaneous regenerative heating of fuel gas and air expands the area of sustainable combustion.
