Study of Lean Premixed Methane Combustion with CO 2 Dilution under Gas Turbine Conditions

Résumé

Among the existing processes for CO2 capture in postcombustion, membrane separation technologies are of great interest because they can provide separation at a greatly reduced energy cost. This technology can only be envisaged, however, if a relatively high content of CO2 is present in the exhaust gas. Exhaust gas recirculation (EGR) is one solution to increase the CO2 content. In this paper, in a first approach, EGR composed only of CO2 was studied. The study of lean premixed methane combustion with CO2 dilution in gas turbine conditions was carried out through an experimental approach performed in a model gas turbine chamber coupled to a kinetic approach. Modeling was carried out using the CHEMKIN package and Cantera1.7, together with the Gas Research Institute Reaction Mechanism Release 3.0, in order to simulate the combustion conditions in terms of burning velocity, temperature, and pollutant emissions (NO and CO) required for proper operation of the system. Particular attention was paid to the case of CO emissions.
