In order to research the effect of fuel and inlet air pressure on the lean blowout (LBO)

the experiment using standard kerosene fuel (RP-3)

diesel and high boiling Fischer-Tropsch oil (FT) in three different combustor inlet pressures was conducted. The results showed that the influence of inlet pressure (19.17%) on LBO was greater than the effect of fuel (6.26%). The main factors of LBO include inlet air pressure

flame volume

combustion temperature

the fuel atomization diameter and the LHV and density of fuel. The flame volume and fuel atomization diameter were mainly affected by the fuel property while the combustion temperature was mainly influenced by the inlet pressure. The change of LBO affected by inlet pressure was attenuated by the affected flame volume and combustion temperature. Fuels with low carbon number and high alkane content may increase the effect of flame volume on LBO

and result in a better LBO in low inlet pressure.
