1 the outer flow passage 14 enables entering the cooling air flow 13 which cools the combustor wall first into the burner section 3 so both air flows ejecting from the inner and outer flow passage 14 15 are mixed with fuel for generating the fuel air mixture 11 which is ignited and burned in the combustion chamber 7 for producing hot gases 8 for powering the turbine stage downstream of the combustion chamber not shown the principle for such the double air passage burner is shown in fig3 the outer flow passage fed by a supply pressure p 2 which is the pressure inside the interspace 9 of the combustor liner surrounds the inner flow passage 15 fed by a supply pressure p 1 which is the pressure inside the plenum 1 the mass flows m 1 and m 2 through the two flow passages are different preferably and can be adjusted suitably optionally each flow path 14 15 can be equipped with swirler 16 17 which may differ between the inner and outer flow path 14 15 respectively the inner flow path 15 contains a bluff body for fuel injection 5 which can be also a means for flow stabilization the exit plane 18 of the inner flow passage 15 may differ from the exit plane 19.
