Abstract
A catalytic ignition system includes a gas fuel supply and a catalytic igniter that is in fluid communication with the gas fuel supply. The catalytic igniter comprises a metallic shell, a catalyst disposed within the metallic shell and a fuel tube that is oriented so as to direct a flow of gas fuel from the gas fuel supply across the catalyst and towards a downstream end of the metallic shell.
Claims20
A catalytic ignition system, comprising:
- a gas fuel supply;
- a catalytic igniter in fluid communication with the gas fuel supply, the catalytic igniter comprising a metallic shell, a catalyst disposed within the metallic shell and a fuel tube, wherein the fuel tube is oriented to direct a flow of gas fuel from the gas fuel supply from an upstream end of the metallic shell, across the catalyst and towards a downstream end of the metallic shell, wherein the gas fuel and catalyst react with ambient air to cause auto-ignition of the gas fuel.
A combustion system, comprising:
- a combustor including a fuel nozzle in fluid communication with a fuel supply and a combustion zone defined downstream from the fuel nozzle;
- and
- a catalytic ignition system, the catalytic ignition system comprising:
- a gas fuel supply;
- and
- one or more catalytic igniters in fluid communication with the gas fuel supply and disposed within the combustor proximate to the combustion chamber, each catalytic igniter comprising a metallic shell, a catalyst disposed within the metallic shell and a fuel tube, wherein the fuel tube is oriented to direct a flow of gas fuel from the gas fuel supply across the catalyst and towards the combustion zone, wherein the gas fuel and catalyst react with ambient air within the combustor to cause auto-ignition of the gas fuel.
