N2  - Flue Gas analyzers are commonly used to determine the molar concentrations of the different flue-gas mixtures species and provide information about the resulting combustion efficiency. Here, a new methodology for quaternary-gas analysis that relies on thermoacoustic technology is described to determine the composition of flue gas mixtures. The flue-gas mixtures resulting from the fossil fuel combustion are allowed to fill in an optimized half-wavelength thermoacoustic engine{u2019}s resonator. Under controlled cooling, spontaneous gas-particle oscillations appear at distinct values of resonance frequencies and onset temperature gradients that particularly depend on the molar concentrations of the quaternary-gas components (CO₂, CO, O₂ and N₂). Operational ternary diagrams, along with respective sensitivity profiles, are discussed in detail. A numerical model is constructed using ANSYS Fluent to assess the performance of the newly introduced methodology. This new sensor offers a simple, reliable, and relatively inexpensive alternative to existing flue-gas analyzers
