Abstract: The invention relates to a method and device for the combustion of fuel with air in a combustion chamber (5). Air is fed via at least one air inlet (6) and fuel is supplied by a plurality of burners (7). Each burner (7) presents an appropriate delay time corresponding to a period of time after which an acoustic impulse in the combustion chamber (5) causes a thermal impulse upon combustion of the fuel supplied via the burner (7). Fuel supply is controlled by the burners (7) so that burner delay times vary considerably. The invention can be used in a gas turbine combustion chamber (5).

Abstract: An acoustic combustor liner for a combustion turbine engine dampens acoustic wave vibrations generated by dynamic pressure variations in the combustion gas. A panel incorporates a meta- structure, also known as a meta-material, acoustic damper, which includes a channel formed in the panel, which is in communication with the combustion gas. The channel defines a channel cavity. A plurality of resonant structures is formed in the channel, respectively defining resonant structure cavities that are in communication with the channel cavity. The channel cavity and each of the respective resonant structure cavities define cavity dimensions that are all smaller than the wavelength(s) of the damped acoustic waves. The meta-structures of the acoustic dampers slow perceived sound speed through their channel and branched structure cavities. The lower perceived sound is attenuated by the composite structural combination of smaller individual cavities, than otherwise would be required for attenuation by traditional, single chamber resonators.

Abstract: An air-cooled component for a combustion turbine, having a monolithic, three-dimensional lattice structure (250) of selectively oriented metallic webs (212, 214, 216) with locally varying lattice density, and asymmetrical- and serpentine-shaped passages (220, 222, 224) formed between the metallic webs for receiving compressed cooling air. The component lattice structure locally varies one or more of lattice density, or cooling airflow rate, or flow volume or flow direction throughout its three-dimensional volume, for locally varying heat transfer and/or vibration damping properties of the component. The lattice structure is incorporated into any one or more of a combustor, or an exhaust, or a transition, or a nozzle, or a liner heatshield, or a tile, or a seal, or an impingement plate, or a liner, or a chute, or a damper, or a ring, or a baffle, or a vane, or a vane ring of a combustion turbine engine.
