The invention being proposed, applies pollution abatement to aircraft and industrial gas turbines. Air from the compressor is divided between primary air for combustion and secondary for dilution, where primary air is directed to a ceramic lined combustion tube where air and fuel are burnt at stoichiometric ratio and then passed through a pollution abatement chamber for non-thermal plasma treating consisting of an electrode rod casing, electrode rods and catalysts between the rod and tube electrodes before rejoining bypass air in a manifold to cool down the flue gases below the creep temperature limit of the turbine stage.
