Abstract

In the annular burner of a 100 kWe micro gas turbine (MGT), combustion begins or is supported by pilot. flames appropriately located. These can be thought as partially stirred reactors in which reagents are considered immiscible at the molecular level and homogeneous in the spatial dimension. The survey reports of a numerical sensitivity analysis developed in two steps. The first on the pilot flame model, focusing on some of the most well-known kinetic schemas of hydrocarbon combustion simulation, has helped to extrapolate the optimal conditions of ignition. Performances of different gaseous biofuels, simulated via the kinetic model’s methane 17, methane 30, and GRI Mech 3.0, to extrapolate, in a sort of principal component analysis to compute NOx production. Operational environment described by the fluid- dynamic parameter M_IXT, that identifies the partially stirred conditions of the flame; temperature at ignition, T_init; the best feeding ratio. GRI Mech 3.0 is the only model able to calculate NOx production and so it was considered at the optimal conditions, by induction, in a sort of extensive meta-analysis.
