There exists a wide range and a considerable potential of alternative (non-certified) gas fuel types. Uncertainty and flexibility of non-conventional fuels’ composition seriously limits the possible exploitation of these energy sources. Therefore developed are both a mathematical model based on the chemical thermodynamics equations, allowing to calculate the composition of the combustion products in terms of suboptimal ratio of fuel — oxidizer, and a computational method for determining the composition of fuel in the combustion process, thus allowing to determine the optimal parameters of combustion. The limitations of the approach are being discussed. Also suggested is the solution of the inverse problem, namely, the determination of the composition and caloric content (enthalpy) of combustion products on the basis of combustion products and their measured volume known qualitative composition flow and temperature (measured process parameters). An assessment of the proposed model being effected, its limitations have been found.
