“…Different reactor networks and different methods to adjust its parameters have been used to study gas turbine combustion chambers. For example, the residence time inside each reactor can be fixed using empirical information such as CO, NO x , and UHC emissions 32 by means of experimental flow visualization 31 or by comparison with CFD results. 33 Taking into account the air or RG mass flow distribution inside the combustion chamber, two different configurations can be considered.…”

This paper compares standard gas turbine combustion chambers and CO2-diluted oxy–fuel combustion chambers for a semiclosed combined cycle at a preliminary design level. To this end, simple chemical reactor networks, based on the well-stirred reactor plus plug flow reactor scheme, are analyzed using the Cantera package and the GRI 3.0 chemical kinetics mechanism. The focus is put on the CO consumption process and the final CO concentration. The behavior of this model suggests the use of the adiabatic equilibrium temperature to characterize the composition at any station inside the chamber and the incipient lean blow-out equilibrium temperature to fix the well-stirred reactor volume. This model is applied to a feasible design point of a power production cycle (combustion exit temperature 1600 K, combustion pressure 30 bar). The fuel is a natural gas with an 87% by volume CH4 content, the ASU stream is a 95% O2 gas, and the recirculated gas is an 82% CO2 gas. The residence times required for CO burnout are approximately 30% greater than those for air combustion for the same conditions, although the required lengths are much closer. The residence times and lengths would be reduced if the combustion exit temperature or the combustion pressure of the cycle was increased.

“…En la literatura científica pueden encontrarse distintas redes de reactores químicos y distintos métodos de ajustar sus parámetros para estudiar las cámaras de combustión de las turbinas de gas. Por ejemplo, el tiempo de residencia en cada reactor se puede fijar usando información empírica como las emisiones de CO, NO x , o hidrocarburos inquemados, UHC, [64], usando visualización experimental del flujo [63] o mediante la comparación con resultados de mecánica de fluidos computacional [65].…”
